performance/stat-prefetch: flush stat corresponding to directory being read in readdir
- delete the entry corresponding to basename of path on which fd is opened from cache stored in parent. This is necessary because readdir changes st_atime. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 221 (stat prefetch implementation) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=221
