md-cache: Do not invalidate cache post set/remove xattr
Since setxattr and removexattr fops cbk do not carry poststat, the stat cache was being invalidated in setxatr/remoxattr cbk. Hence the further lookup wouldn't be served from cache. To prevent this invalidation, md-cache is modified to get the poststat in set/removexattr_cbk in dict. Co-authored with Xavi Hernandez. Change-Id: I6b946be2d20b807e2578825743c25ba5927a60b4 fixes: bz#1586018 Signed-off-by: Xavi Hernandez <xhernandez@redhat.com> Signed-off-by: Poornima G <pgurusid@redhat.com>
