Hi Al, The following three patches implement the extra functionality you wanted on top of the inode lock breakup. The first patch lifts the i_lock up out of writeback_single_inode(), the second implements RCU freeing of inodes via SLAB_DESTROY_BY_RCU, and the third converts inode hash lookup operations to use RCU list walks. Comments are welcome. Cheers, Dave. -- 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
