Brian Foster 41b9d7263e xfs: trim eofblocks before collapse range ... xfs_collapse_file_space() currently writes back the entire file undergoing collapse range to settle things down for the extent shift algorithm. While this prevents changes to the extent list during the collapse operation, the writeback itself is not enough to prevent unnecessary collapse failures. The current shift algorithm uses the extent index to iterate the in-core extent list. If a post-eof delalloc extent persists after the writeback (e.g., a prior zero range op where the end of the range aligns with eof can separate the post-eof blocks such that they are not written back and converted), xfs_bmap_shift_extents() becomes confused over the encoded br_startblock value and fails the collapse. As with the full writeback, this is a temporary fix until the algorithm is improved to cope with a volatile extent list and avoid attempts to shift post-eof extents.
