So, the transaction close is in btrfs_evict_inode, which sounds like a deadlock recently fixed by this commit: http://git.kernel.org/?p=linux/kernel/git/mason/linux-btrfs.git;a=commit;h=aa38a711a893accf5b5192f3d705a120deaa81e0 If you pull the for-linus branch from today, hopefully the problem will be gone. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
