* performance/stat-prefetch: introduce sp_fd_ctx_t to hold context of fdsRaghavendra G2009-09-082-11/+144
| | | | | | | | | | | | | | - we need following extra members along with cache 1. basename of path on which fd is opened. This is necessary to search for cached entry in fd based fops. 2. inode corresponding to dirname of path on which fd is opened. This is necessary to get cache where entry corresponding to file on which fd is opened. Signed-off-by: Anand V.

| | | | | | | | | | | - stat-prefetch aims to optimize operations like 'ls -l' where a readdir is immediately followed by stat calls on each of the directory entry read.
