I don't really like it. There's nothing XFS-specific here - it's the same problem with direct reclaim calling back into the FS and causing massive amounts of problems. If we want to fix this class of problems we just need to do the same thing ext4 and btrfs already do and refuse to call the allocator from reclaim context. Just curious, how much stack does the path up to generic_perform_write use? -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
