2011-06-21PM: Free memory bitmaps if opening /dev/snapshot failsMichal Kubecek
When opening /dev/snapshot device, snapshot_open() creates memory bitmaps which are freed in snapshot_release(). But if any of the callbacks called by pm_notifier_call_chain() returns NOTIFY_BAD, open() fails, snapshot_release() is never called and bitmaps are not freed. Next attempt to open /dev/snapshot then triggers BUG_ON() check in create_basic_memory_bitmaps(). This happens e.g. when vmwatchdog module is active on s390x.

2011-06-21Revert "drm/i915: Kill GTT mappings when moving from GTT domain"Eric Anholt
This reverts commit 4a684a4117abd756291969336af454e8a958802f. Userland has always been required to set the object's domain to GTT before using it through a GTT mapping, it's not something that the kernel is supposed to enforce. (The pagefault support is so that we can handle multiple mappings without userland having to pin across them, not so that userland can use GTT after GPU domains without telling the kernel). Fixes 19.2% +/- 0.8% (n=6) performance regression in cairo-gl firefox-talos-gfx on my T420 latop. Signed-off-by: Keith Packard <keithp@keithp.com>

1. If the intention is to coalesce requests 'prev' and 'req' then we have to ensure at least that we have a layout starting at req_offset(prev). 2. If we're only requesting a minimal layout of length desc->pg_count, we need to test the length actually returned by the server before we allow the coalescing to occur. 3. We need to deal correctly with (pgio->lseg == NULL) 4. Fixup the test guarding the pnfs_update_layout. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2011-06-20vfs: i_state needs to be 'unsigned long' for nowLinus Torvalds
Commit 13e12d14e2dc ("vfs: reorganize 'struct inode' layout a bit") moved things around a bit changed i_state to be unsigned int instead of unsigned long. That was to help structure layout for the 64-bit case, and shrink 'struct inode' a bit (admittedly that only happened when spinlock debugging was on and i_flags didn't pack with i_lock). However, Meelis Roos reports that this results in unaligned exceptions on sprc, and it turns out that the bit-locking primitives that we use for the I_NEW bit want to use the bitops. Which want 'unsigned long', not 'unsigned int'. We really should fix the bit locking code to not have that kind of requirement, but that's a much bigger change. So for now, revert that field back to 'unsigned long' (but keep the other re-ordering changes from the commit that caused this). Andi points out that we have played games with this in 'struct page', so it's solvable with other hacks too, but since right now the struct inode size advantage only happens with some rare config options, it's not worth fighting. It _would_ be worth fixing the bitlocking code, though. Especially since there is no type safety in the bitlocking code (this never caused any warnings, and worked fine on x86-64, because the bitlocks take a 'void *' and x86-64 doesn't care that deeply about alignment). So it's currently a very easy problem to trigger by mistake and never notice.
