LU-11104 mdt: rename may cause deadlock

In rename locking, there are two situations we need to lock target
parent before source parent:
1. source parent is subdir of target parent.
2. source and target parents are both stripes of the same directory,
   and stripe index of source parent is after that of target parent.

But the check for the second situation is missing, which may cause
deadlock if another thread is taking stripe locks of their parent.

Cleanup mdd_is_subdir().

LU-11102 ldlm: run local lock bl_ast only when necessary

LDLM local lock will be canceled after use, and it should only
run bl_ast if it needs to trigger Commit-on-Sharing, otherwise
if this bl_ast does nothing, it will prevent subsequent
operations to run bl_ast again, therefore Commit-on-Sharing
can't be triggered.

For example, a concurrent setattr on a striped directory and
rename under this directory:
1. setattr takes UPDATE lock of directory, but not unlock it yet
(i.e., this lock is not downgraded to COS lock).
2. a concurrent 'mv' under this directory will first getattr file by
name, this getattr will take UPDATE lock of this directory, which is
racing with setattr, but this getattr is not a distributed operation,
and the lock still has writer (by setattr), bl_ast does nothing.
3. setattr unlocks this UPDATE lock.
4. rename tries to lock UPDATE lock of this directory, but this lock
was bl_ast was run before(though nothing did), it won't run again,
rename will wait until setattr transaction commit.

To fix this, run local lock bl_ast only when it will trigger
Commit-on-Sharing.

Add sanity.sh test_415 to verify this.

LU-9538 mdt: Lazy size on MDT

The design of Lazy size on MDT (LSOM) does not guarantee the
accuracy. A file that is being opened for a long time might
cause inaccurate LSOM for a very long time. And also eviction or
crash of client might cause incomplete process of closing a file,
thus might cause inaccurate LSOM. A precise LSOM could only be read
from MDT when 1) all possible corruption and inconsistency caused
by client eviction or client/server crash have all been fixed by
LFSCK and 2) the file is not being opened for write.
In the first step of implementing LSOM, LSOM will not be accessible
from client. Instead, LSOM values can only be accessed on MDT. Thus,
no interface or logic codes will be added on client side to enabled
the access of LSOM from client side.
The LSOM will be saved as an EA value on MDT.
LSOM includes both the apparent size and also the disk usage of
the file.
Whenever a file is being truncated, the LSOM of the file on MDT
will be updated.
Whenever a client is closing a file, ll_prepare_close() will send
the size and blocks to the MDS. The MDS will update the LSOM of
the file if the file size or block size is being increased.

LU-11131 target: keep reply data bit set on failover

The following scenario leads to failure of recent reint rpc:

1. mdt server has number of rpcs being handled, rpc 1 from client A
and rpc 2 from client B.

2. shutdown for the server starts

3. rpc 1 is processed, reply data is added, but client A gets ENODEV
in reply (ptlrpc_send_reply()) as shutdown is running

3. shutdown reaches class_disconnect_exports() and links an export A
to the list of zombie exports

4. obd_zombid thread wakes up and destroy the export A, which includes
freeing of reply data list with clearing bits in
lut->lut_reply_bitmap (tgt_free_reply_data())

5. export B is still processing the rpc 2 and looks for free bit in
the lut->lut_reply_bitmap to store reply data
(tgt_add_reply_data()). If it finds a bit which has been just freed by
obd_zombid thread, then reply data from export A will get overwritten
in reply_data file with reply data from export B

6. after failover, reply data gets restored with
tgt_reply_data_init(). The reply data of client A is missing

7. client A reconnects and resends its rpc 1. Server does not find
reply data and processes the rpc as if it has not been seen yet. In
case of unlink, the directory entry already does not exist so rpc 1
fails

The fix is to not free bits in lut->lut_reply_bitmap in case of
failover.

Test illustrating the issue is added.

The patch that landed for LU-7236 introduced new sysfs entries
which were done wrong.

1) For idle_timeout it returns -ERANGE for
   any value passed in expect setting idle_timeout to zero. This
   does not match what the commit message said for LU-7236. So
   I changed lprocfs_str_with_units_to_s64() into kstrtouint()
   since a signed 64 bit timeout is not needed. Using kstrtouint()
   ensures that negative values are not possible and also cap the
   value to CONNECTION_SWITCH_MAX since the max of 4 billion
   seconds is over kill.

2) For the next procfs idle_connect it is really a write only file
   but it was treated as both read and write. There is no need for
   the osc_idle_connect_seq_show() function.

3) Lastly no more stuffing new entries into proc or debugfs. For
   this patch convert these new proc entries to sysfs. It seems
   to be a common occurrence so add LPROC_SEQ_* to spelling.txt
   so checkpatch will complain about using LPROC_SEQ_* which will
   go away.

LU-7816 quota: add default quota setting support

Similar function which is motivated by GPFS which is friendly
feature for cluster administrators to manage quota.

Lazy Quota default setting support, here is basic idea:

Default quota setting is global quota setting for user, group,
project quotas, if default quota is set for one quota type,
newer created users/groups/projects will inherit this setting
automatically, since Lustre itself don't have ideas when new
users created, they could only know when this users trying to
acquire space from Lustre.

So we try to implement lazy quota setting inherit, Slave firstly
check if there exists default quota setting, if exists, it will
force slave to acquire quota from master, and master will detect
whether default quota is set, then it will set this quota and also
return proper grant space to slave.

To implement this and reuse existed quota APIs, we try to manage
the default quota in the quota record of 0 id, and enforce the
quota check when reading the quota recored from disk.

In the current Lustre implementation, the grace time is either
the time or the timestamp to be used after some quota ID exceeds
the soft limt, then 48bits should be enough for it, its high 16bits
can be used as kinds of quota flags, this patch will use one of
them as the default quota flag.

The global quota record used by default quota will set its soft
and hard limit as zero, its grace time will contain the default flag.

Use lfs setquota -U/-G/-P <mnt> to set default quota.
Use lfs setquota -u/-g/-p foo -d <mnt> to set foo to use default quota
Use lfs quota -U/-G/-P <mnt> to show default quota.

LU-11004 ptlrpc: Serialize procfs access to scp_hist_reqs using mutex

scp_hist_reqs list can be quite long thus a lot of
userland processes can waste CPU power in spinlock cycles.

LU-10527 obdclass: don't recycle loghandle upon ENOSPC

In llog_cat_add_rec(), upon -ENOSPC error being returned from
llog_cat_new_log(), don't reset "cathandle->u.chd.chd_current_log"
to NULL.
Not doing so will avoid to have llog_cat_declare_add_rec() repeatedly
and unnecessarily create new+partially initialized LLOGs/llog_handle
and assigned to "cathandle->u.chd.chd_current_log", this without
llog_init_handle() never being called to initialize
"loghandle->lgh_hdr".

Also, unnecessary LASSERT(llh) has been removed in
llog_cat_current_log() as it prevented to gracefully handle this
case by simply returning the loghandle.
Thanks to S.Cheremencev (Cray) to report this.

Both ways to fix have been kept in patch as the 1st part allows for
better performance in terms of number of FS operations being done
with permanent changelog's ENOSPC condition, even if this covers
a somewhat unlikely situation.

LU-10175 ldlm: handle lock converts in cancel handler

- Use cancel portals and high-priority handling for lock
  converts. Update ldlm_cancel_handler to understand
  LDLM_CONVERT RPC for that.
- Use ns_dirty_age_limit for lock convert - don't convert too old
  locks.
- Check for empty converts and skip such
