* kill nameidata * argument; map the 3 bits in ->flags anybody cares
about to new MAY_... ones and pass with the mask.
* kill redundant gfs2_iop_permission()
* sanitize ecryptfs_permission()
* fix remaining places where ->permission() instances might barf on new

The obvious next target in that direction is permission(9)

Kmem cache passed to constructor is only needed for constructors that are
themselves multiplexeres. Nobody uses this "feature", nor does anybody uses
passed kmem cache in non-trivial way, so pass only pointer to object.
Non-trivial places are:
arch/powerpc/mm/init_64.c
arch/powerpc/mm/hugetlbpage.c
This is flag day, yes.

Move declarations of some macros, which should be in fact functions to
quotaops.h. This way they can be later converted to inline functions
because we can now use declarations from quota.h. Also add necessary
includes of quotaops.h to a few files.

The comment above the function says one of its return value is -EIO,
and also the caller of diAlloc() checks for -EIO:
struct inode *ialloc(struct inode *parent, umode_t mode)
{
...
rc = diAlloc(parent, S_ISDIR(mode), inode);
if (rc) {
jfs_warn("ialloc: diAlloc returned %d!", rc);
if (rc == -EIO)
make_bad_inode(inode);
...

Convert jfs_ioctl over to not use the BKL. The only potential race
I could see was with two ioctls in parallel changing the flags
and losing the updates. Use the i_mutex to protect against this.

Stop the JFS filesystem from using iget() and read_inode(). Replace
jfs_read_inode() with jfs_iget(), and call that instead of iget(). jfs_iget()
then uses iget_locked() directly and returns a proper error code instead of an
inode in the event of an error.
jfs_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.

JFS is missing a memory barrier needed to close the critical section before
clearing the lock bit. Use lock bitops for this.
unlock_page() has a second barrier after clearing the lock, which is
required because it checks whether the waitqueue is active without locks.
Such a barrier is not required here because the waitqueue spinlock is
always taken (something to think about if performance is an issue).

When JFS decides to drop a dirty metapage, it simply clears the META_dirty
bit and leave alone the PG_dirty and PAGECACHE_TAG_DIRTY bits.
When such no-write page goes to metapage_writepage(), the `relic'
PAGECACHE_TAG_DIRTY tag should be cleared, to prevent pdflush from
repeatedly trying to sync them. This is done through
set_page_writeback(), so call it should be called in all cases. If
no I/O is initiated, end_page_writeback() should be called immediately.
This is how __block_write_full_page() does things.
