performance/io-cache: pass appropriate op_errno even during successful

2012-03-09T03:22:02+00:00

reads.

An op_errno equal to ENOENT with op_ret equal to zero is used by
storage/posix xlator to indicate EOF. NFS relies on this protocol
for correct functioning.

performance/io-cache: move mem-pool initialisation to init.

2012-03-08T17:10:02+00:00

mem-pool is global structure which is stored in ioc-inode-table and hence
can be initialised in init.

perf/md-cache: hold lock on modification of md_cache structure

2012-03-01T03:45:45+00:00

as it is possible that multiple fops can alter the content of
md-cache structure from inode-ctx, we need to safe-guard the
issue of corruption due to race conditions.

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.
