[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.

vfs: add rcu argument to ->get_acl() callback Add a rcu argument to the ->get_acl() callback to allow get_cached_acl_rcu() to call the ->get_acl() method in the next patch.

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.

fs: make helpers idmap mount aware Extend some inode methods with an additional user namespace argument. A filesystem that is aware of idmapped mounts will receive the user namespace the mount has been marked with. This can be used for additional permission checking and also to enable filesystems to translate between uids and gids if they need to. We have implemented all relevant helpers in earlier patches. As requested we simply extend the exisiting inode method instead of introducing new ones. This is a little more code churn but it's mostly mechanical and doesnt't leave us with additional inode methods.
