mempool: adjustments in pool sizes

2012-02-22T12:23:48+00:00

* while creating 'rpc_clnt', the caller knows what would be the ideal
  load on it, so an extra argument to set some pool sizes

* while creating 'rpcsvc', the caller knows what would be the ideal
  load of it, so an extra argument to set request pool size

* cli memory footprint is reduced

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.

statedump: do not print the inode number in the statedump

2011-10-01T12:55:22+00:00

    Since gfid is used to uniquely identify a inode, in the statedump
    printing inode number is not necessary. Its suffecient if the gfid
    of the inode is printed. And do not print the the inodelks, entrylks
    and posixlks if the lock count is 0.

performance/io-cache,quick-read: increase cache-size limit

2011-09-29T16:39:50+00:00

Does the following:
1. Increases cache-size limit from 6GB to 32GB.
2. Prevents 'volume set'from failing when cache-size is set over the
limit. Just issues a warning.
3. Performs check on cache-size by comparing with total system memory
available in init () and reconfigure () methods.
