LU-15509 lnet: Ping buffer ref leak in lnet_peer_data_present

lnet_peer_merge_data() and lnet_peer_set_primary_data() are
responsible for dropping the reference on the ping buffer that is
taken by lnet_peer_push_event() and lnet_discovery_event_reply().
However, there are some error paths in lnet_peer_data_present()
where we do not call either lnet_peer_merge_data() or
lnet_peer_set_primary_data(). In these cases, we need to drop
the reference on the ping buffer otherwise it will leak.

The main idea of this fix is next, when OST is lost during
lod_ost_alloc_rr() and MDT does not have precreated objects for it
lod_ost_alloc_rr()->..->lod_qos_declare_object_on() would sleep while

lod_ost_alloc_qos() waiting lq_rw_sem for write, after statfs update.
Whith a fix sleep is limited and allocation would going through
lod_ost_alloc_rr(). For read lq_rw_sem is shared and stripe allocation
would skip OST without objects.

lod_ost_alloc_rr() refills OST pool with a lq_rw_sem for write, when
lq_rr.lqr_flags has LQ_DIRTY. This should happen only when OST is
added/removed. No need to set LQ_DIRTY for lq_rr when statfs get
error, this flag does not affect any change for pool list at
lod_qos_calc_rr().

Change behaviour for lod_check_and_reserve_ost(), it  would sleep
during object allocation for speed 2 only.

For Linux 5.5 kernel a patch to improve nokey names was landed
that removed several variables that Lustre's llite and mdt layer

Second change for Ubuntu is several backports to handle a few
variables changing across different kernel versions. One is the name
change of DCACHE_ENCRYPTED_NAME and the other being
is_chipertext_name. So the simpler approach Ubuntu took was to use
fscrypt_prepare_lookup() and fscrypt_is_nokey_name() to work
around these changes. Lastly the good news is for 5.12 the

Add RPCs to iotrace debugging.

To avoid creating too much debug output, this debug
ignores the possiblity that an RPC contains non-contiguous
extents.  Thus the eventual visualization will act as
though the RPC is a continuous whole.  I judge this to be
superior to the amount of log data and complexity of
capturing each extent separately.  If that level of detail
is needed, a higher debug level can be used.

LU-15483 tests: Improve test 398b

Test 398b is currently only writing 3 MiB (12 MiB/4) of
data from each thread in the racing set (4 DIO, 4 BIO).
This is such a small amount that it's probably finishing
too quickly to generate the intended overlap & races most
of the time.

It also currently writes only at PAGE_SIZE, which excludes
a lot of possible races.

This is currently a pretty fast test - ~ 2 seconds on my
local machine, similar on Maloo - so let's have it write 4
times more data and use 4 different block sizes, so it will
hit more races.

This is 16x more I/O, but the test still only takes around
16 seconds on my local machine.

This is motivated by difficulties dealing with rare
failures while developing the LU-13799 patch series and
hoping to make them easier to catch.

commit c2b6d621c4ffe9936adf7a55c8b1c769672c306f
Author: Al Viro <viro@zeniv.linux.org.uk>
Date: Thu Jun 28 15:53:17 2018 -0400 new primitive: discard_new_inode()

find_inode_fast() returns -ESTALE, but iget_locked() replaces
it to the NULL and finally ldiskfs_inode_attach_jinode()
returns -ENOMEM.

So this check in osd_iit_iget() doesn't work.

if (rc == -ENOENT || rc == -ESTALE)
    RETURN(SCRUB_NEXT_CONTINUE);

As a solution we can skip an inode if -ENOMEM returned

LU-15132 mdc: Use early cancels for hsm requests

HSM RELEASE and RESTORE requests take EX layout lock on the MDT side.
So the client can use early cancel for its local lock on the resource
to limit the contention (mdt side).

This patch does not pack ldlm request inside the hsm request because
the field (RMF_DLM_REQ) does not exist in the request. Adding this
field inside the request would break compatibility with _old_ servers.

LU-15776 tgt: fix transaction handling in tgt_brw_write()

Hotfix to prevent possible data loss during WRITE replay.
Since commit f0f92773ee18 from LU-14187 the obd_commitrw()
may restart write transaction in OFD and MDT. That causes
transaction number to be assigned multiple times if such
restart happens. Without flag tti_mult_trans the first
transaction number is stored only so later one could remain
not applied causing data loss after recovery.

Patch sets tti_mult_trans for tgt_brw_write() so the latest
transaction number will be used as request transno.

Which goes into an infinite loop:
ofd_commitrw_write()->osd_write_commit()->osd_ldiskfs_map_inode_pages()
    ->ldiskfs_map_blocks()->ofd_commitrw_write()

The cause is that:
For 64K PAGE_SIZE blocks allocation/mapping. m_lblk should be the
first un-allocated block if m_lblk points at an already allocated
block when create = 1, ldiskfs_map_blocks() will just return with
already allocated blocks and without allocating any new requested
blocks for the extent.

This stuck issue won't happen on 4K PAGE_SIZE. Because for
PAGE_SIZE = blocksize case, if m_lblk points at an already
allocated block it will point at an un-allocated block in next
restart transaction, because the already mapped block/page will
be filtered out in next restart transaction via flag
OBD_BRW_DONE in osd_declare_write_commit().

When this parameter is 1, new empty directories configured as

LU-15848 ldiskfs: escape encrypted file names

When a Lustre MDT is mounted as ldiskfs, the names of the encrypted
files have to be escaped to avoid breaking the shell.
On CentOS 7, the LDISKFS_ENCRYPT_FL flag does not exist. So we add it,
and when the target is mounted as ldiskfs (LDISKFS_MOUNT_DIRDATA flag
not present) we critical-encode encrypted file names before
presentation. And conversely, we critical-decode names upon lookup.
On CentOS 8, the LDISKFS_ENCRYPT_FL flag exists. The fscrypt functions
from kernel 4.18 are also wired up, but they all refer to -EOPNOTSUPP
or equivalent, so they cannot be used to present usable names. So when
the target is mounted as ldiskfs (LDISKFS_MOUNT_DIRDATA flag not
present) we proceed to critical-encoding of encrypted file names
before presentation, and to critical-decoding upon lookup.

LU-15810 sec: fix enc dir migration

Now that the encryption context is stored in an xattr named
