* performance/io-cache: fix memory leak.Raghavendra G2009-10-281-0/+1
| | | | | | | | | - page table of cache was not being destroyed in ioc_forget. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 335 (Io-cache optimization) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=335
* performance/io-cache: fix double free.Raghavendra G2009-10-281-1/+1
| | | | | | | | | | | - the destroyer function passed to rbthash_table_init is used to free the data. The data being inserted is page and it is destroyed in ioc_page_destroy. Hence no destroyer function needs to be passed to rbthash_table_init. Signed-off-by: Anand V.

* performance/io-cache: change data structure used to store page-cache.Raghavendra G2009-10-285-69/+90

* performance/write-behind: fix to bug in setattr which was causing frames to ↵Raghavendra G2009-10-201-1/+2
| | | | | | | | | | | | | | | be missed. - local->file was being assigned even before file pointer was got from any of the fds opened on the inode, thus making local->file to be NULL. In wb_setattr_cbk, since local->file is NULL (and hence file passed to wb_process_queue), wb_process_queue does not resume the pending operations queued for the file. Signed-off-by: Anand V.

| | | | | | | | | | | | | - change sp_lookup and sp_lookup_cbk to support sending lookups when needed. lookups might need to be sent in fops like open, chmod, chown etc which operate on a path, since the actual lookup sent to stat-prefetch by its parent xlators is not propagated down the xlator tree if the path is cached.
