It hasn't come up often, I looked through old logs at FB and we hit it a handful of times over the last year. The rest are other corners he hit during testing Filipe Manana (4) commits (+68/-10): Btrfs: fix race when reusing stale extent buffers that leads to BUG_ON (+19/-0) Btrfs: fix race between block group creation and their cache writeout (+27/-4) Btrfs: fix panic when starting bg cache writeout after IO error (+10/-4) Btrfs: fix crash after inode cache writeback failure (+12/-2) Total: (4) commits fs/btrfs/extent-tree.c | 31 +++++++++++++++++++++++++++---- fs/btrfs/extent_io.c | 19 +++++++++++++++++++ fs/btrfs/free-space-cache.c | 14 ++++++++++++-- fs/btrfs/ordered-data.c | 14 ++++++++++---- 4 files changed, 68 insertions(+), 10 deletions(-)
