[PATCH 0/7] btrfs: fix a bug with truncation and writeback and cleanups

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

The first patch fixes a bug where we can up persisting a file extent item
that crosses the i_size boundary, making btrfs check complain because it
won't find checksum items beyond the i_size boundary. Details in the change
log. The rest are several cleanups in related code that popped up while
debugging the issue.

Filipe Manana (7):
  btrfs: truncate ordered extent when skipping writeback past i_size
  btrfs: use variable for end offset in extent_writepage_io()
  btrfs: split assertion into two in extent_writepage_io()
  btrfs: add unlikely to unexpected error case in extent_writepages()
  btrfs: consistently round up or down i_size in btrfs_truncate()
  btrfs: avoid multiple i_size rounding in btrfs_truncate()
  btrfs: avoid repeated computations in btrfs_mark_ordered_io_finished()
