Dave Chinner 3ed3a4343b xfs: truncate delalloc extents when IO fails in writeback ... We currently use block_invalidatepage() to clean up pages where I/O fails in ->writepage(). Unfortunately, if the page has delalloc regions on it, we fail to remove the delalloc regions when we invalidate the page. This can result in tripping a BUG() in xfs_get_blocks() later on if a direct IO read is done on that same region - the delalloc extent is returned when none is supposed to be there. Fix this by truncating away the delalloc regions on the page before invalidating it. Because they are delalloc, we can do this without needing a transaction. Indeed - if we get ENOSPC errors, we have to be able to do this truncation without a transaction as there is no space left for block reservation (typically why we see a ENOSPC in writeback).
