performance/io-cache: check for non-null gfid before calling inode_path

2013-07-11T02:44:25+00:00

A new non-linked inode is added to lru list. Hence it might be possible
that gfid might be NULL when inode_dump is called. To pass asserts in
inode_path, we've to check for non-null gfid before invoking that
procedure.

glusterfs: discard (hole punch) support

2013-06-13T21:37:43+00:00

Add support for the DISCARD file operation. Discard punches a hole
in a file in the provided range. Block de-allocation is implemented
via fallocate() (as requested via fuse and passed on to the brick
fs) but a separate fop is created within gluster to emphasize the
fact that discard changes file data (the discarded region is
replaced with zeroes) and must invalidate caches where appropriate.

gluster: add fallocate fop support

2013-06-13T21:37:21+00:00

Implement support for the fallocate file operation. fallocate
allocates blocks for a particular inode such that future writes
to the associated region of the file are guaranteed not to fail
with ENOSPC.

This patch adds fallocate support to the following areas:

	- libglusterfs
	- mount/fuse
	- io-stats
	- performance/md-cache,open-behind
	- quota
	- cluster/afr,dht,stripe
	- rpc/xdr
	- protocol/client,server
	- io-threads
	- marker
	- storage/posix
	- libgfapi

performance/write-behind: Enable write-behind when strict_O_DIRECT is not set.

2013-05-28T17:05:28+00:00

When open() with O_DIRECT happens, write-behind was being disabled for the
fd irrespective of strict_O_DIRECT option. This commit disables write-behind
only when strict_O_DIRECT is enabled.

md-cache: support negative xattr entries

2013-05-25T18:35:50+00:00

Add support for negative xattr caching. For this, we need
to fetch xattrs in every opportunity (including readdirplus)
in order to treat missing key in cached dict as negative entry.

This is crucial to detect missing ACL xattrs in Samba workload.

quick-read: prune cache on write/[f]truncate

2013-05-20T22:05:53+00:00

Cache needs to be pruned on write and [f]truncate. The lack of this
is causing Samba ping-pong test to return wierd 'data increment' values
during startup.

mount/fuse: enable fuse real async dio when available

2013-05-16T00:19:06+00:00

fuse has support for optimized async. direct I/O handling via the
FUSE_ASYNC_DIO init flag. Enable FUSE_ASYNC_DIO when advertised
by fuse.

performance/write-behind: fix dio hang

Also fix a hang observed during aio-stress testing due to conflicting
request handling in write-behind. Overlapping requests are skipped
in pick_winds and may never continue when the conflicting write in
progress returns. Add a wb_process_queue() call after a non-wb request
completes to keep the queue moving.
