[GFS2] Make headers compile on their own As per Jan Engelhardt's comments, this should make all the headers compile on their own by including and/or declaring structures early.

GFS2: Increase the max number of ACLs This patch increases the maximum number of ACLs from 25 to 300 for a 4K block size. The value is adjusted accordingly if the block size is smaller. Note that this is an arbitrary limit with a performance tradeoff, and that the physical limit is slightly over 500.

fs: take the ACL checks to common code Replace the ->check_acl method with a ->get_acl method that simply reads an ACL from disk after having a cache miss. This means we can replace the ACL checking boilerplate code with a single implementation in namei.c.

gfs2: Switch to generic xattr handlers Switch to the generic xattr handlers and take the necessary glocks at the layer below. The following are the new xattr "entry points"; they are called with the glock held already in the following cases: gfs2_xattr_get: From SELinux, during lookups. gfs2_xattr_set: The glock is never held. gfs2_get_acl: From gfs2_create_inode -> posix_acl_create and gfs2_setattr -> posix_acl_chmod. gfs2_set_acl: From gfs2_setattr -> posix_acl_chmod.
