v1->v2: - Rebased onto misc-next, dropping everything that's been merged so far. - Fixed "btrfs: splice remaining dirty_bg's onto the transaction dirty bg list" to handle the btrfs_alloc_path() failure and cleaned up the error handling as a result of that change. - dropped "btrfs: don't clear ret in btrfs_start_dirty_block_groups" as I fixed it differently in "btrfs: splice remaining dirty_bg's onto the transaction dirty bg list" - Added a link to Zygo's original report in "btrfs: add asserts for deleting backref cache nodes". - Clarified the error condition that lead to the WARN_ON() in the changelog for "btrfs: do not WARN_ON() if we can't find the reloc root". - Added the stack trace that the error injection triggered in order to get the error that happened in "btrfs: abort the transaction if we fail to inc ref in btrfs_copy_root".
--- Original email --- Hello, A lot of these were in previous versions of the relocation error handling patches. I added a few since the last go around. All of these do not rely on the error handling patches, and some of them are quite important otherwise we get corruption if we get errors in certain spots. There's also a few lockdep fixes and such. These really need to go in ASAP, regardless of when the relocation error handling patches are merged. They're mostly small and self contained, the only "big" one being the one that tracks the root owner for relocation reads, which is to resolve the remaining class of lockdep errors we get because of an improper lockdep class set on the extent buffer.
