Hi, Are you folks still seeing ext4_mb_generate_buddy or ext4_mb_release_inode_pa EXT4-fs errors? I think I may have found a fix for this problem. Or at least, I've found one of the causes. If we get a memory allocation failure from ext4_mb_new_inode_pa(), it can cause these errors. Actually triggering it is a bit tricky, but it looks like we saw it hit when a task which was running under high memory pressure (because it was running right against its cgroup memory limit) core dump. Anyway, if you are still seeing these issues, this patch might help you out: http://patchwork.ozlabs.org/patch/375106/ If it works out for you, please let me know.
