Here is my current patchset for improving vfs locking scalability. Since last posting, I have fixed several bugs, solved several more problems, and done an initial sweep of filesystems (autofs4 is probably the trickiest, and unfortunately I don't have a good test setup here for that yet, but at least I've looked through it). Also started to tackle files_lock, vfsmount_lock, and inode_lock. (I included my mnt_want_write patches before the vfsmount_lock scalability stuff because that just made it a bit easier...). These appear to be the problematic global locks in the vfs. It's running stably here so far on basic stress testing here on several file systems (xfs, tmpfs, ext?). But it still might eat your data of course. Would be very interested in any feedback.
