BUG: 329 (Replacing memory allocation functions with mem-type functions)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=329
This results in a crash in STACK_UNWIND after a call bail out.
Since the call bail does not occur in the context of an xlator,
the old_THIS in STACK_UNWIND is handed a global_xlator which did
not have its ctx set, resulting in a NULL de-reference.

BUG: 734 (keep only the working/usable code in build tree to focus more on development)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=734
This patch adds a facility by which each translator
keeps track of the average latency of a FOP from
its point of view. That is, the duration between
the translator handing over the call to a lower-level
translator and the reply coming back.
The latency measurement is off by default, and can
be toggled by sending SIGUSR2 to the GlusterFS process.
Latency data is printed as part of the process state dump.

Submitted-by: Krishna Srinivas <krishna@gluster.com>
NOTE: fixed compilation issues in posix.c introduced while merging
storage/posix polls for FS/kernel being functional by issuing
statvfs() call. In case statvfs expires the timer, storage/posix will
send CHILD_DOWN to upper translator. Ultimately this will cause
protocol/server to disconnect all clients connected and also cleans up
the data structures. Hence if soft lockup or other kernel bug causes
backend FS to hang, the clients will not be hung.

Hello,
This patch fixes bug 397: dictionary (de)serialization used pointer
casting which forced word-alignment on (at least) armv5tel, causing
corruption while writing and reading buffers into memory. It also adds
some debugging (more information in case of errors).
I tried to send this a few times already but I think it got bounced from
the list.
Greetings,

BUG: 227 (replicate selfheal does not remove directory with contents in it)
URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=227
Support for auxiliary group ids is needed for transmission
of more than one group id right through the xlator tree
so that posix can use these group ids to perform
in-house permission tests. The in-house permission checks are
needed so that we do not have to depend on non-POSIX calls
like setfs[ug]id for changing the user for each fop.
The setfs[ug]id are also limited since they do not allow setting
multiple group id as required for operation with NFS, which sends
us all the group ids for a process issuing file system requests.

The janitor thread deletes all files and directories in
the "/" GF_REPLICATE_TRASH_DIR directory. This directory
is used by replicate self-heal to dump files and
directories it deletes.
This is needed because letting replicate walk the directory
tree and delete a directory and all its children is too racy.
Instead, replicate self-heal only does an atomic rename(),
and the janitor thread takes care of actually deleting them.
