md-cache: support negative xattr entries

2013-06-08T21:50:34+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

2013-06-08T21:49:59+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.

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

2013-05-30T00:04:11+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.

performance/io-cache: Avoid double mem_put in ioc_readv

2013-05-07T11:39:44+00:00

On readv error io-cache frame->local is not set to NULL
so the local is mem_put in STACK_DESTROY as well. This
patch sets frame->local to NULL in all cases.

performance/write-behind: guarantee non-overlapping concurrent writes

2013-03-07T07:30:14+00:00

Maintain a list of writes (either written behind or SYNC) which are
currently "in progress" (i.e, STACK_WIND'ed towards server) and hold
off any new STACK_WIND of write (either written behind or SYNC) which
overlaps with any of the "in progress" writes.

This is a guarantee which AFR's eager-lock depends upon (though not
strictly a write-behind requirement)

open-behind: translator to perform open calls in background

2013-02-06T21:16:08+00:00

This is functionality peeled out of quick-read into a separate
translator.

Fops which modify the file (where it is required to perform the
operation on the true fd) will trigger and wait for the backend
open to succeed and use that fd.

Fops like fstat() readv() etc. will use anonymous FD (configurable)
when original fd is unopened at the backend.
