Darrick J. Wong 0520483177 xfs: don't drop errno values when we fail to ficlone the entire range ... commit 7ce31f20a0771d71779c3b0ec9cdf474cc3c8e9a upstream. Way back when we first implemented FICLONE for XFS, life was simple -- either the the entire remapping completed, or something happened and we had to return an errno explaining what happened. Neither of those ioctls support returning partial results, so it's all or nothing. Then things got complicated when copy_file_range came along, because it actually can return the number of bytes copied, so commit 3f68c1f562 tried to make it so that we could return a partial result if the REMAP_FILE_CAN_SHORTEN flag is set. This is also how FIDEDUPERANGE can indicate that the kernel performed a partial deduplication. Unfortunately, the logic is wrong if an error stops the remapping and CAN_SHORTEN is not set. Because those callers cannot return partial results, it is an error for ->remap_file_range to return a positive quantity that is less than the @len passed in. Implementations really should be returning a negative errno in this case, because that's what btrfs (which introduced FICLONE{,RANGE}) did. Therefore, ->remap_range implementations cannot silently drop an errno that they might have when the number of bytes remapped is less than the number of bytes requested and CAN_SHORTEN is not set. Found by running generic/562 on a 64k fsblock filesystem and wondering why it reported corrupt files.
