The patch titled
ext4: fix wrong gfp type under transaction
has been removed from the -mm tree. Its filename was
ext4-fix-wrong-gfp-type-under-transaction.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: ext4: fix wrong gfp type under transaction
From: Josef Bacik <jbacik@xxxxxxxxxx>
This fixes the allocations with GFP_KERNEL while under a transaction problems
in ext4. This patch is the same as its ext3 counterpart, just switches these
to GFP_NOFS.
