To fix it\nright way we need to mark _dentry_ as unsuitable for mounting\nupon; new flag (DCACHE_CANT_MOUNT) is protected by d_flags and\ni_mutex on the inode in question. Set it (with dont_mount(dentry))\nin unlink/rmdir/etc., check (with cant_mount(dentry)) in places\nin namespace.c that used to check for S_DEAD. Setting S_DEAD\nis still needed in places where we used to set it (for directories\ngetting killed), since we rely on it for readdir/rmdir race\nprevention.\n\n2) rename()/mount() protection has another bogosity - we unhash\nthe target before we\u0027d checked that it\u0027s not a mountpoint. Fixed.\n\n3) ancient bogosity in pivot_root() - we locked i_mutex on the\nright directory, but checked S_DEAD on the different (and wrong)\none.

It actually\nimplements the tracking of the number of writers to a mount.\nHowever, it causes scalability problems because there can be\nhundreds of cpus doing open()/close() on files on the same mnt at\nthe same time. Even an atomic_t in the mnt has massive scalaing\nproblems because the cacheline gets so terribly contended.\n\nThis uses a statically-allocated percpu variable. All want/drop\noperations are local to a cpu as long that cpu operates on the same\nmount, and there are no writer count imbalances. Writer count\nimbalances happen when a write is taken on one cpu, and released\non another, like when an open/close pair is performed on two\n\nUpon a remount,ro request, all of the data from the percpu\nvariables is collected (expensive, but very rare) and we determine\nif there are any outstanding writers to the mount.\n\nI\u0027ve written a little benchmark to sit in a loop for a couple of\nseconds in several cpus in parallel doing open/write/close loops.\n\nhttp://sr71.net/~dave/linux/openbench.c\n\nThe code in here is a a worst-possible case for this patch. It\ndoes opens on a _pair_ of files in two different mounts in parallel.\nThis should cause my code to lose its \"operate on the same mount\"\noptimization completely. This worst-case scenario causes a 3%\ndegredation in the benchmark.\n\nI could probably get rid of even this 3%, but it would be more\ncomplex than what I have here, and I think this is getting into\nacceptable territory. In practice, I expect writing more than 3\nbytes to a file, as well as disk I/O to mask any effects that this\nhas.\n\n(To get rid of that 3%, we could have an #defined number of mounts\nin the percpu variable.
