Instead of calling mdt_agent_record_update, which calls
cdt_llog_process, once for every HAL, build a list of the cookies to
update with their status and call mdt_agent_record_update just once

The option flag for stripe-size in the getstripe command was changed
in Lustre 1.8.  To detect the correct flag to use, the help was

LU-9874 osd-ldiskfs: simplify project transfer codes

Currently, osd-ldiskfs call __ldiskfs_ioctl_project()
to transfer project quota which is user ioctl for ext4 which
will start a transaction, and reserve credits, this is not
right logic with Lustre.

Lustre have started a transaction handle and credits should be
reserved during declare phase, so calling _ldiskfs_ioctl_project()
here will cause nested handle starting, which is not a problem for
JBD2 because it will attach current thread's handle if transaction
have been started, but in this case it will ignore credits
reservation.

Also Lustre don't need inode mutex protection for
project transfer, we don't need write inode in transfer codes,
it will be done when dirty inode is called. Setting attr
have reserved enough credits for project transfer, we need
fix agent inode transfering.

This patch makes codes logic clear, also fix credits
reservation for DNE agent inode transfering.

LU-8276 ldlm: Make lru clear always discard read lock pages

A significant amount of time is sometimes spent during
lru clearing (IE, echo 'clear' > lru_size) checking
pages to see if they are covered by another read lock.
Since all unused read locks will be destroyed by this
operation, the pages will be freed momentarily anyway,
and this is a waste of time.

This patch sets the LDLM_FL_DISCARD_DATA flag on all the PR
locks which are slated for cancellation by
ldlm_prepare_lru_list when it is called from
ldlm_ns_drop_cache.

The case where another lock covers those pages (and is in
use and so does not get cancelled by lru clear) is safe for
a few reasons:

1. When discarding pages, we wait (discard_cb->cl_page_own)
until they are in the cached state before invalidating.
So if they are actively in use, we'll wait until that use
is done.

2. Removal of pages under a read lock is something that can
happen due to memory pressure, since these are VFS cache
pages. If a client reads something which is then removed
from the cache and goes to read it again, this will simply
generate a new read request.

This has a performance cost for that reader, but if anyone
is clearing the ldlm lru while actively doing I/O in that
namespace, then they cannot expect good performance.

In the case of many read locks on a single resource, this
improves cleanup time dramatically.  In internal testing at
Cray with ~80,000 read locks on a single file, this improves
cleanup time from ~60 seconds to ~0.5 seconds.  This also
slightly improves cleanup speed in the case of 1 or a few
read locks on a file.

The mdd layer uses cfs_time_xxx_64() for 64 bit time percision.

The patch "LU-6401 uapi: turn lustre_param.h into a proper
UAPI header" removed various user land functions used to
validate poolnames and file system names were removed. The

any possible user land software directly interfacing to the

of formating the backend file system no kernel interaction
doesn't happen until it tries to mount the MDT/OST/MGT which

the file system name verification to mkfs.lustre to warn
users long before they try to mount anything.

Secondly we remove the verify_poolname() in lfs.c since
it duplicates extract_fsname_poolname() in obd.c. Their
is no need to do the same test twice. The function
pool_cmd() calls the ioctl for pool handling which in

the user what mistake they did for their pool command.
For the MGS kernel code mgs_extract_fs_pool() was checking
MTI_NAME_MAXLEN instead of LUSTRE_MAXFSNAME. Also use
LUSTRE_MAXFSNAME instead of the raw number in the function

Modify the IOC_LIBCFS_GET_PEER_NI ioctl (which is new in the

LU-9480 lnet: implement Peer Discovery

Implement Peer Discovery.

A peer is queued for discovery by lnet_peer_queue_for_discovery().
This set LNET_PEER_DISCOVERING, to indicate that discovery is in
progress.

The discovery thread lnet_peer_discovery() checks the peer and
updates its state as appropriate.

If LNET_PEER_DATA_PRESENT is set, then a valid Push message or
Ping reply has been received. The peer is updated in accordance
with the data, and LNET_PEER_NIDS_UPTODATE is set.

If LNET_PEER_PING_FAILED is set, then an attempt to send a Ping
message failed, and peer state is updated accordingly. The discovery
thread can do some cleanup like unlinking an MD that cannot be done
from the message event handler.

If LNET_PEER_PUSH_FAILED is set, then an attempt to send a Push
message failed, and peer state is updated accordingly. The discovery
thread can do some cleanup like unlinking an MD that cannot be done
from the message event handler.

If LNET_PEER_PING_REQUIRED is set, we must Ping the peer in order to
correctly update our knowledge of it. This is set, for example, if
we receive a Push message for a peer, but cannot handle it because
the Push target was too small. In such a case we know that the
state of the peer is incorrect, but need to do extra work to obtain
the required information.

If discovery is not enabled, then the discovery process stops here
and the peer is marked with LNET_PEER_UNDISCOVERED. This tells the
discovery process that it doesn't need to revisit the peer while
discovery remains disabled.

If LNET_PEER_NIDS_UPTODATE is not set, then we have reason to think
the lnet_peer is not up to date, and will Ping it.

The peer needs a Push if it is multi-rail and the ping buffer
sequence number for this node is newer than the sequence number it
has acknowledged receiving by sending an Ack of a Push.

If none of the above is true, then discovery has completed its work
on the peer.

Discovery signals that it is done with a peer by clearing the
LNET_PEER_DISCOVERING flag, and setting LNET_PEER_DISCOVERED or
LNET_PEER_UNDISCOVERED as appropriate. It then dequeues the peer
and clears the LNET_PEER_QUEUED flag.

When the local node is discovered via the loopback network, the
peer structure that is created will have an lnet_peer_ni for the
local loopback interface. Subsequent traffic from this node to
itself will use the loopback net.

discovery. This change adds the thread and the infrastructure
that starts and stops it. The thread itself does trivial work.

Peer Discovery gets its own event queue (ln_dc_eqh), a queue

for peers waiting for an event (ln_dc_working), a wait queue
head so the thread can sleep (ln_dc_waitq), and start/stop
state (ln_dc_state).

Peer discovery is started from lnet_select_pathway(), for
GET and PUT messages not sent to the LNET_RESERVED_PORTAL.
This criterion means that discovery will not be triggered by

with its lpn_peer pointer. This hold is only removed when that
pointer is assigned a new value or the lnet_peer_net is freed.
Just removing an lnet_peer_net from the lp_peer_nets list does
not release this hold, it just prevents new lookups of the
lnet_peer_net via the lnet_peer.

Each lnet_peer_ni has a hold on the lnet_peer_net it links to

list does not release this hold, it just prevents new lookups

This ensures that given a lnet_peer_ni *lpni, we can rely on
lpni->lpni_peer_net->lpn_peer pointing to a valid lnet_peer.

LU-9480 lnet: preferred NIs for non-Multi-Rail peers

When a node sends a message to a peer NI, there may be
a preferred local NI that should be the source of the
message. This is in particular the case for non-Multi-
Rail (NMR) peers, as an NMR peer depends in some cases
on the source address of a message to correctly identify
its origin. (This as opposed to using a UUID provided by
a higher protocol layer.)

Implement this by keeping an array of preferred local
NIDs in the lnet_peer_ni structure. The case where only
a single NID needs to be stored is optimized so that this
can be done without needing to allocate any memory.

A flag in the lnet_peer_ni, LNET_PEER_NI_NON_MR_PREF,
indicates that the preferred NI was automatically added
for an NMR peer. Note that a peer which has not been
explicitly configured as Multi-Rail will be treated as
non-Multi-Rail until proven otherwise. These automatic
preferences will be cleared if the peer is changed to
Multi-Rail.

- lnet_peer_ni_set_non_mr_pref_nid()
  set NMR preferred NI for peer_ni
- lnet_peer_ni_clr_non_mr_pref_nid()
  clear NMR preferred NI for peer_ni
- lnet_peer_clr_non_mr_pref_nids()

sanity-lfsck tests 9a and 9b check the version of the MDS
to see if the test should be run. Unfortunately, the
server_version variable is never initialized and the tests
are skipped.

For sanity-lfsck tests 9a and 9b, get the server version
using the lustre_version_code routine.
