parser: make the parser thread safe.

2013-09-10T08:14:02+00:00

The volfile parser thread safe by guarding the parsing phase
in a mutex. Thread safety becomes a problem when there are multiple
glfs_t objects created by gfapi and all of them potentially parse
the respective volfiles at the same time.

mount/fuse: perform lookup() on inodes linked through readdirplus

2013-09-10T00:19:09+00:00

Some xlators still require lookup() fop to be sent for proper working.
This patch remembers inodes which have been linked through readdiprlus
and makes the resolver send lookups on them.

Also, introduce and use context count for inode table.

call-stub: internal refactor

2013-09-05T13:27:05+00:00

- re-structure members of call_stub_t with new simpler layout
- easier to inspect call_stub_t contents in gdb now
- fix a bunch of double unrefs and double frees in cbk stub
- change all STACK_UNWIND to STACK_UNWIND_STRICT and thereby fixed
  a lot of bad params
- implement new API call_unwind_error() which can even be called on
  fop_XXX_stub(), and not necessarily fop_XXX_cbk_stub()

cluster/afr: Perform delayed changelog wakeups for anon fd

2013-06-10T20:04:21+00:00

Problem:
Nfs xlator never does open on a file for performing writes,
afr does not perform changelog wakeup for this fd so operations
which do metadata operations as soon as the data operations are
completed perceive a delay od 'post-op-delay-secs'.

Fix:
Perform changelog wakeup on anon-fd if the fd with same pid is
not present in inode-list.

Note:
This approach is a short-term fix. A proper fix needs a new domain
for taking metadata locks so that data/metadata locks don't compete
with each other.
