LU-9793 ptlrpc: Do not map unrecognized ELDLM errnos to EIO

The lustre_errno_hton and lustre_errno_ntoh functions map between
host and network error numbers before they are sent over the network.
If an errno is unrecognized then it is mapped to EIO.

However an optimization for x86 and i386 architectures replaced the
functions with macros that simply return the original errno. The
result is that x86 and i386 return the original values for ELDLM
errnos and all other architectures return EIO. This difference is
known to break glimpse lock callback handling which depends on clients
responding with ELDLM_NO_LOCK_DATA. The difference in errnos may
result in other as yet unidentified bugs.

The fix defines mappings for the ELDLM errors that leaves the values
unchanged. Error numbers not found in the mapping tables are still
mapped to EIO.

LU-9906 clio: use pagevec_release for many pages

When Lustre releases cached pages, it always uses
page_release, even when releasing many pages.

When clearing OST ldlm lock lrus in parallel with lots of
cached data, the ldlm_bl threads spend most of their time
contending for the zone lock taken by page_release.
Also, when osc_lru_reclaim kicks in when there's not enough
LRU slots during I/O, the contention on zone lock kills
I/O performance.

Switching to pagevec when we expect to actually release the
pages (discard_pages, truncate, lru reclaim) brings
significant performance benefits as shown below.

This patch introduces cl_pagevec_put() to release the pages
in batches using pagevec, which is essentially calling
release_pages().

LU-11418 llog: refresh remote llog upon -ESTALE

If a distributed transaction is aborted, it will invalidate all
objects involved, which include remote catalog and update logs.

So llog_cat_declare_add_rec() will refresh remote llog upon -ESTALE,
but it only does this for chd_current_log, not chd_next_log.

If an aborted transaction happens to invalidate catalog only, and
leave chd_current_log valid, which will cause subsequent operations
fail to create chd_next_log.

This patch prepares both current and next log of catalog before
declare_write in llog_cat_declare_add_rec().

LU-10937 mgc: restore mgc binding for sptlrpc

The work for LU-9034 mapped config logs to separate mgc devices.
This change prevented the ability to configure sptlrpc. A later
work around was introduced in LU-9567. Recently it was reported
that the work around introduced can now cause a MGC failover
panic. This patch is the proper fix in that the sptlrpc is
properly bound to an mgc device.

The sptlrpc config record expects 2 pieces of data:

  *  [0]: fs_name/target_name,
  *  [1]: rule string

What was happening is that when you set cfg_instance it was used
to create a new instance name of the form fsname-%p. For sptlrpc
it expects it to only be fsname. The solution is to test if the
config record is for sptlrpc and in that can keep the first
record field as is. With this change we can drop cfg_obdname
which only sptlrpc used.

LU-11130 osd-ldiskfs: create non-empty local agent symlinks

e2fsck doesn't like zero-sized symlink inodes created by
osd_create_local_agent_inode().  Store the FID of the remote

It would be better to just migrate the whole symlink instead

there is not a hard link to the symlink (which POSIX allows,

LU-10406 mdt: invalidate cache upon LDLM lock

given new components (like LFSCK) can access storage w/o LDLM

invalidate local cache explicitly once LDLM lock is granted.

also, OSP should invdalite any state requested before invalidation
request as LDLM lock and request can be handled in different

sent first, the target MDT serviced it first, but the reply got
delayed for a reason. in the meantime LDLM lock was requested,
granted and received by the source MDT before reply for get_attr.
IOW, we get a state with old (potentially stale) state and LDLM
lock granted.

LU-10472 osd-ldiskfs: T10PI between RPC and BIO

When OST recieves bulk write RPC, the T10PI guard tag will be
generated during the process of calculating RPC checksum with
T10PI type. Guard tags of each sector will be copied to the
BIO integrity payload to avoid recalculating of guard tags.

When OST reads data from disk, the T10PI guard tags will be
copied from BIO integrity payload. These guard tags will be
reused for calculation the RPC checksum with T10PI type, thus
no recalcuating of guard tags is needed either.

However, if the data that the client is reading is cached
in memory, the guard tags need to be calculated based on the
cached data, since there is no place to plug the guard tags
to the page cache on OSS.

Some modification to Linux kernel is needed:

1) We can pass “struct bio *” and  to the integrity
generate/verify methods, and struct blk_integrity_exchg
has bi_idx which is the current bio_vec index.

2) bio_integrity_prep accepts optional pointers to integrity
generation/verification methods. The optional methods take
priority over the ones registered by the device.

These two modification enable Lustre (and other file systems) to
integrate with BIO for integrity verification/generation. Any private
data need during data integrity generation/verification process can
be attached to bio->bi_private. Instead of calculating guard tags,
Lustre generation method will copy the guard tags from existing
buffer. And instead of (or besides of) data integrity verification,
Lustre verification method will copy the guard tags to internal
buffer for further usage.

Besides of these changes, two Linux kernel patches are applied:

1) The first problem is that bio_integrity_verify() doesn't verify
the data integrity at all. In that function, after reading the data,
bio->bi_idx will be equal to bio->bi_vcnt because of bio_advance(),
so bio_for_each_segment_all() should be used, not
bio_for_each_segment(). And also, bio_advance() should not change
the integrity data bio_integrity_advance() unless the BIO is being
trimmed.
Linux-commit: 63573e359d052e506d305c263576499f06355985

2) The second patch fixes a problem of the sd_dif_complete(). When
sector offset is larger then 2^32, the mapping from physical
reference tag to the virtual values expected by block layer will be
wrong.

LU-11423 osc: Do not walk full extent list

It is only possible to merge with the extent immediately
before or immediately after the one we are trying to add,
so do not continue to walk the extent list after passing
that extent.

This has a significant impact when writing large sparse
files, where most writes create a new extent, and many
extents are too distant to be merged with their neighbors.

Writing 2 GiB of data randomly 4K at a time, we see an
improvement of about 15% with this patch.

to find reviewers for an existing patch.

Usage:

lfs mirror write {--mirror-id|-N <mirror_id>}
[--inputfile|-i <input_file>] <mirrored_file>

Options:

--mirror-id|-N <mirror_id>
  This  option  indicates  the  content of which mirror specified by
  mirror_id needs to be written. The mirror_id is the numerical unique
  identifier for a mirror.

--inputfile|-i <input_file>
  The path name of the input file, if not specified, the standard
  input stream will be used. The input stream or input_file cannot
  be the same mirrored file as the mirrored_file.

This command will issue a RESYNC lease write lock to notify MDS to
prepare destination mirror for the write (instantiate components of
the mirror), then client copy data from a file or STDIN to the
