[PATCH] btrfs: mask out gfp flasg in releasepage
btree_releasepage is a callback and can be passed unknown gfp flags and then
they may end up in kmem_cache_alloc called from alloc_extent_state, slab
allocator will BUG_ON when there is HIGHMEM or DMA32 flag set.
This may happen when btrfs is mounted from a loop device, which masks out
__GFP_IO flag. The check in...

[PATCH] Btrfs: do not hold the write_lock on the extent tree while logging V2
...g while doing allocations and such which is not
good. This patch fixes this by dropping the write lock before we do
anything heavy and re-acquire it when it is done. We also need to take a
ref on the em''s in case their corresponding pages are evicted and mark them
as being logged so that releasepage does not remove them and doesn''t remove
them from our local list. Thanks,
