Chris Mason 8b8b08cbfb Btrfs: fix delalloc accounting after copy_from_user faults ... Commit 56244ef151 was almost but not quite enough to fix the reservation math after btrfs_copy_from_user returned partial copies. Some users are still seeing warnings in btrfs_destroy_inode, and with a long enough test run I'm able to trigger them as well. This patch fixes the accounting math again, bringing it much closer to the way it was before the sectorsize conversion Chandan did. The problem is accounting for the offset into the page/sector when we do a partial copy. This one just uses the dirty_sectors variable which should already be updated properly.
