ocfs2: add ocfs2_xattr_set_handle
This function is used to set xattr's in a started transaction. It is only called during inode creation inode for initial security/acl xattrs of the new inode. These xattrs could be put into ibody or extent block, so xattr bucket would not be use in this case. Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
