To do that requires communication with all other CPUs\nthat may have taken a reference count.\n\nWe can make refcounts more scalable in a couple of ways, involving keeping\ndistributed counters, and checking for the global-zero condition less\nfrequently.\n\n- check the global sum once every interval (this will delay zero detection\n for some interval, so it\u0027s probably a showstopper for vfsmounts).\n\n- keep a local count and only taking the global sum when local reaches 0 (this\n is difficult for vfsmounts, because we can\u0027t hold preempt off for the life of\n a reference, so a counter would need to be per-thread or tied strongly to a\n particular CPU which requires more locking).\n\n- keep a local difference of increments and decrements, which allows us to sum\n the total difference and hence find the refcount when summing all CPUs. Then,\n keep a single integer \"long\" refcount for slow and long lasting references,\n and only take the global sum of local counters when the long refcount is 0.\n\nThis last scheme is what I implemented here. Attached mounts and process root\nand working directory references are \"long\" references, and everything else is\na short reference.\n\nThis allows scalable vfsmount references during path walking over mounted\nsubtrees and unattached (lazy umounted) mounts with processes still running\nin them.\n\nThis results in one fewer atomic op in the fastpath: mntget is now just a\nper-CPU inc, rather than an atomic inc; and mntput just requires a spinlock\nand non-atomic decrement in the common case. However code is otherwise bigger\nand heavier, so single threaded performance is basically a wash.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n" }, { "commit": "4b936885ab04dc6e0bb0ef35e0e23c1a7364d9e5", "tree": "a0173d27c1ce39f173be404d269c2f15144072ab", "parents": [ "873feea09ebc980cbd3631b767356ce1eee65ec1" ], "author": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Fri Jan 07 17:50:07 2011 +1100" }, "committer": { "name": "Nick Piggin", "email": "npiggin@kernel.dk", "time": "Fri Jan 07 17:50:32 2011 +1100" }, "message": "fs: improve scalability of pseudo filesystems\n\nRegardless of how much we possibly try to scale dcache, there is likely\nalways going to be some fundamental contention when adding or removing children\nunder the same parent.

The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "3836a03d978e68b0ae00d3589089343c998cd4ff", "tree": "8a7e71fa5af7d87784145e14141a997b8a5b6e3f", "parents": [ "83c0fb6500b13c9b7564fe453b76356dc58415d4" ], "author": { "name": "Eric Paris", "email": "eparis@redhat.com", "time": "Tue Mar 09 22:23:01 2010 -0500" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 12 16:25:23 2010 -0800" }, "message": "anon_inodes: mark the anon inode private\n\nInotify was switched to use anon_inode instead of its own private filesystem\nwhich only had one inode in commit c44dcc56d2b5c7 \"switch inotify_user to\nanon_inode\"\n\nThe problem with this is that now the inotify inode is not a distinct inode\nwhich can be managed by LSMs. userspace tools which use inotify were allowed\nto use the inotify inode but may not have had permission to do read/write type\noperations on the anon_inode.
