It was in 3.11.4 and 3.10.15 (and 3.12-rc3). It breaks bcache's writeback mode by calling bch_writeback_data without setting cache_bio (it's more visible here[1]). There's a bit of indirection through closure calls, but it could never work. |1] http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c0f04d88e46d14de51f4baebb6efafb7d59e9f96&context=8 -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
