The server's callback client should stop trying to connect to the
client's callback server as soon as it gets ECONNREFUSED.
The NFS server's callback client does not call rpc_ping(), but appears
to have it's own "ping" procedure, so it wasn't covered by commit

When both blocking and completion callbacks are queued for lock,
the dlm would always deliver the completion callback (cast) first.
In some cases the blocking callback (bast) is queued before the
cast, though, and should be delivered first. This patch keeps
track of the order in which they were queued and delivers them
in that order.
This patch also keeps track of the granted mode in the last cast
and eliminates the following bast if the bast mode is compatible
with the preceding cast mode. This happens when a remotely mastered
lock is demoted, e.g. EX->NL, in which case the local node queues
a cast immediately after sending the demote message. In this way
a cast can be queued for a mode, e.g. NL, that makes an in-transit
bast extraneous.

fallocate() may potentially instantiate blocks past EOF, depending
on the flags used when it is called.
e2fsck currently has a test for blocks past i_size, and it
sometimes trips up - noticeably on xfstests 013 which runs fsstress.
This patch from Jiayang does fix it up - it (along with
e2fsprogs updates and other patches recently from Aneesh) has

803bf5ec25 ("fs/exec.c: restrict initial
stack space expansion to rlimit") attempts to limit the initial stack to
20*PAGE_SIZE. Unfortunately, in attempting ensure the stack is not
reduced in size, we ended up not changing the stack at all.
This size reduction check is not necessary as the expand_stack call does
this already.
This caused a regression in UML resulting in most guest processes being
killed.

- Usage of nfsd_sync_dir and write_inode_now has been replaced with the
commit_metadata function that takes a svc_fh.
- The commit_metadata function calls the commit_metadata export_op if it's
there, or else falls back to sync_inode instead of fsync and write_inode_now
because only metadata need be synced here.
- nfsd4_sync_rec_dir now uses vfs_fsync so that commit_metadata can be static

cachefiles_delete_object() can race with rename. It gets the parent directory
of the object it's asked to delete, then locks it - but rename may have changed
the object's parent between the get and the completion of the lock.
However, if such a circumstance is detected, we abandon our attempt to delete
the object - since it's no longer in the index key path, it won't be seen
again by lookups of that key. The assumption is that cachefilesd may have
culled it by renaming it to the graveyard for later destruction.

This is a trivial patch to remove unnecessary condition.
load_segment_summary() checks crc of segment_summary OR crc of whole
log data blocks based on boolean argument full_check. However,
callers of the function pass only 1 as full_check, which means only
whole log data blocks checking code is running all the time.
This patch deletes the condition and full_check argument and also

clause, for it is nolonger used anymore.

and an array no longer makes sense for looking up by pool id. Use an
