xlators/features/namespace: Add namespace xlator and link into brick graph
The following release-3.8-fb branch patch is upstreamed: > features/namespace: Add namespace xlator and link into brick graph > Commit ID: dbd30776f26e > https://review.gluster.org/#/c/18041/ > By Michael Goulet <mgoulet@fb.com> Changes in this patch: Removes extra config.h and namespace.h file in namespace.c Adds default_getspec_cbk to libglusterfs.sym Rename dict_for_each to dict_foreach_inline Remove fd.h header file stack.h Add test case for truncate, open and symlink This patch is required to forward port io-threads namespace patch. Updates: #401 Change-Id: Ib88c95b89eecee9b8957df8a4c8712c899c761d1 Signed-off-by: Varsha Rao <varao@redhat.com>
