I've reproduced this one here and have a patch in testing. Thanks! Bug reproduced reliably in 2.6.29-rc3 testing (did not include fix). Numerous tests using btrfs-unstable from 29 Jan (which includes a fix for this bug) on uncompressed filesystems have passed cleanly, so the patch looks good. Testing included both multi- and single device filesystems for completeness. Side note: testing of fix for #12563 on same btrfs-unstable base has resulted in occasional I/O stalls on one subset of my test configurations using compressed filesystems, implying that there may be other holes to close. However, Chris has previously noted that we may not be ready for compressed fstress testing just yet. Great, I'll close this one down. |
