core: utilize mempool for frame->local allocations

2012-02-21T10:42:09+00:00

in each translator, which uses 'frame->local', we are using
GF_CALLOC/GF_FREE, which would be costly considering the
number of allocation happening in a lifetime of 'fop'. It
would be good to utilize the mem pool framework for xlator's
local structures, so there is no allocation overhead.

locks: perform inode_ref of pl_update_refkeeper outside locked region

2011-10-28T12:02:03+00:00

Performing inode_ref inside the critical section of pl_update_refkeeper
(around pl_inode_t->mutex) causes a deadlock with inode_table_t->lock.
The other thread (process state dump) holds the inode_table_t->lock first
to loop over inodes and then while dumping an inode's lock context, tries
to acquire pl_inode_t->mutex thereby completing the deadlock.

The fix is to perform inode_ref outside the critical section in
pl_update_refkeeper
