Posix translator returns pre and postbufs in the dict in {F}REMOVEXATTR fops.
These iatts are further cached at layers like md-cache.
Shard translator, in its current state, simply returns these values without
updating the aggregated file size and block-count.
This patch fixes this problem.

The claim that Fedora package guidelines do not require this scheme is a non-argument. Not only do they not require it, they don't prohibit it either. (And you can't prove a negative. It's a specious argument.) Change-Id: I7748c7531d52dedd71b3a7f5df049742258a6aba Fixes: #1126 Signed-off-by: Kaleb S. KEITHLEY <kkeithle@redhat.com>
There was a critical flaw in the previous implementation of open-behind. When an open is done in the background, it's necessary to take a reference on the fd_t object because once we "fake" the open answer, the fd could be destroyed. However as long as there's a reference, the release function won't be called. So, if the application closes the file descriptor without having actually opened it, there will always remain at least 1 reference, causing a leak. To avoid this problem, the previous implementation didn't take a reference on the fd_t, so there were races where the fd could be destroyed while it was still in use. To fix this, I've implemented a new xlator cbk that gets called from fuse when the application closes a file descriptor. The whole logic of handling background opens have been simplified and it's more efficient now. Only if the fop needs to be delayed until an open completes, a stub is created. Otherwise no memory allocations are needed. Correctly handling the close request while the open is still pending has added a bit of complexity, but overall normal operation is simpler.

Problem: See github issue for details. Fix: -In lookup if the entry exists in 2 out of 3 bricks, don't fail the lookup with ENOENT just because there is an entrylk on the parent. Consider quorum before deciding. -If entry FOP does not succeed on quorum no. of bricks, do not perform new entry mark.

To keep consistency inside transactions started by locking an entry or an inode, this change delays the removal of entries that are currently locked by one or more clients. Once all locks are released, the removal is processed. It has also been improved the detection of stale inodes in the locking code of EC.

Problem: In a replicate/arbiter volume if file creations or writes fails on quorum number of bricks and on one brick it is due to ENOSPC and on other brick it fails for a different reason, it may fail with errors other than ENOSPC in some cases. Fix: Prioritize ENOSPC over other lesser priority errors and do not set op_errno in posix_gfid_set if op_ret is 0 to avoid receiving any error_no which can be misinterpreted by __afr_dir_write_finalize(). Also removing the function afr_has_arbiter_fop_cbk_quorum() which might consider a successful reply form a single brick as quorum success in some cases, whereas we always need fop to be successful on quorum number of bricks in arbiter configuration.
