Hi Al, These as the first versions of the patches that remove the inode lock from the writeback lists, superblock inode lists and the inode hash table. I haven't polished them at all, but they appear to work ok so I thought I'd send them out for comments before I went to bed... With these patches the inode_lock pretty much disappears from my lock_stat profiles, with the writeback list lock being the most contended of the replacements on an 8-way machine. 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
