ceph: fix posix ACL hooks The merge of commit 7221fe4c2ed7 ("ceph: add acl for cephfs") raced with upstream changes in the generic POSIX ACL code (eg commit 2aeccbe957d0 "fs: add generic xattr_acl handlers" and others). Some of the fallout was fixed in commit 4db658ea0ca ("ceph: Fix up after semantic merge conflict"), but it was incomplete: the set_acl inode_operation wasn't getting set, and the prototype needed to be adjusted a bit (it doesn't take a dentry anymore).

ceph: fix ceph_set_acl() If acl is equivalent to file mode permission bits, ceph_set_acl() needs to remove any existing acl xattr. Use __ceph_setxattr() to handle both setting and removing acl xattr cases, it doesn't return -ENODATA when there is no acl xattr. Signed-off-by: Yan, Zheng <zheng.z.yan@intel.com>

ceph: include the initial ACL in create/mkdir/mknod MDS requests Current code set new file/directory's initial ACL in a non-atomic manner. Client first sends request to MDS to create new file/directory, then set the initial ACL after the new file/directory is successfully created. The fix is include the initial ACL in create/mkdir/mknod MDS requests. So MDS can handle creating file/directory and setting the initial ACL in one request.
