Since we don't need to maintain large pools of messages, we can just
use the standard mempool_t. We maintain a msgpool 'wrapper' because we
need the mempool_t* in the alloc function, and mempool gives us only
pool_data.

ceph_sb_to_client and ceph_client are really identical, we need to dump
one; while function ceph_client is confusing with "struct ceph_client",
ceph_sb_to_client's definition is more clear; so we'd better switch all
call to ceph_sb_to_client.
-static inline struct ceph_client *ceph_client(struct super_block *sb)
-{
- return sb->s_fs_info;

Following Nick Piggin patches in btrfs, pagecache pages should be

policies.
Also, using add_to_page_cache_lru instead of using a private

Use a 32-bit popcnt instruction for __arch_hweight32(), even on
x86-64. Even though the input register will *usually* be
zero-extended due to the standard operation of the hardware, it isn't
necessarily so if the input value was the result of truncating a
64-bit operation.
Note: the POPCNT32 variant used on x86-64 has a technically
unnecessary REX prefix to make it five bytes long, the same as a CALL
instruction, therefore avoiding an unnecessary NOP.

We use this value to find an inode within the hash bucket, so we can't
change this without re-hashing the inode. For now, treat this value
as immutable.
Eventually, we should probably use an inode number change on a path
based operation to indicate that the lookup cache is invalid, but that's
a bit more code to deal with.

To avoid problems like the one fixed by Stephane Eranian in 3de29ca, now
we'll got this instead:
bench/sched-messaging.c:259: error: negative width in bit-field ‘<anonymous>’
bench/sched-messaging.c:261: error: negative width in bit-field ‘<anonymous>’
Which is rather cryptic, but is how BUILD_BUG_ON_ZERO works, so kernel
hackers should be already used to this.
With it in place found some problems, fixed by changing the affected
variables to sensible types or changed some OPT_INTEGER to OPT_UINTEGER.
Next csets will go thru converting each of the remaining OPT_ so that
review can be made easier by grouping changes per type per patch.
