clean up handling of special client pids
- no need to name a lower boundary [drop GF_CLIENT_PID_MIN] - drop utility function to decide about pid speciality [gf_pid_client_check()]; when we implement uniform policy for special pids, use just comparison with GF_CLIENT_PID_MAX (currently such uniform policy exists in io-threads, where special clients get lowest priority) - io-threads: drop numeric literal, use GF_CLIENT_PID_MAX - xattr flipping (in fuse): - fuse_xattr_alloc_default() made static - avoid compiler warnings wrt. partial enum traversal in the switch by not casting the original numeric value to gf_client_pid_t (enum) type - trim down the switch to those cases with which there is something to do [GF_CLIENT_PID_GSYNCD, GF_CLIENT_PID_HADOOP] - eliminate the (theoretical) chance of succesfully returning from fuse_flip_xattr_ns() with unallocated nkey [as was the case with pids GF_CLIENT_PID_{MIN,MAX,DEFRAG}] Change-Id: Ic2b83b908d8e3be23a7fba1e5895869828a6194b BUG: 765433 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: http://review.gluster.com/3170 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>
