Omar Sandoval 313facc5bd btrfs: remove dead snapshot-aware defrag code ... Snapshot-aware defrag has been disabled since commit 8101c8dbf6 ("Btrfs: disable snapshot aware defrag for now") almost 6 years ago. Let's remove the dead code. If someone is up to the task of bringing it back, they can dig it up from git. This is logically a revert of commit 38c227d87c ("Btrfs: snapshot-aware defrag") except that now we have to clear the EXTENT_DEFRAG bit to avoid need_force_cow() returning true forever. The reasons to disable were caused by runtime problems (like long stalls or memory consumption) on heavily referenced extents (eg. thousands of snapshots). There were attempts to fix that but never finished. Current defrag breaks the extent references and some users prefer that behaviour over the one implemented by snapshot aware (ie. keeping links for defragmentation). To enable both usecases we'd need to extend defrag ioctl but let's do that properly from scratch.
