      "message": "[PATCH] fdtable: Implement new pagesize-based fdtable allocator\n\nThis patch provides an improved fdtable allocation scheme, useful for\nexpanding fdtable file descriptor entries.  The main focus is on the fdarray,\nas its memory usage grows 128 times faster than that of an fdset.\n\nThe allocation algorithm sizes the fdarray in such a way that its memory usage\nincreases in easy page-sized chunks. The overall algorithm expands the allowed\nsize in powers of two, in order to amortize the cost of invoking vmalloc() for\nlarger allocation sizes. Namely, the following sizes for the fdarray are\nconsidered, and the smallest that accommodates the requested fd count is\nchosen:\n\n    pagesize / 4\n    pagesize / 2\n    pagesize      \u003c- memory allocator switch point\n    pagesize * 2\n    pagesize * 4\n    ...etc...\n\nUnlike the current implementation, this allocation scheme does not require a\nloop to compute the optimal fdarray size, and can be done in efficient\nstraightline code.\n\nFurthermore, since the fdarray overflows the pagesize boundary long before any\nof the fdsets do, it makes sense to optimize run-time by allocating both\nfdsets in a single swoop.  Even together, they will still be, by far, smaller\nthan the fdarray.  The fdtable-\u003eopen_fds is now used as the anchor for the\nfdset memory allocation.\n\nSigned-off-by: Vadim Lobanov \u003cvlobanov@speakeasy.net\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] fdtable: Make fdarray and fdsets equal in size\n\nCurrently, each fdtable supports three dynamically-sized arrays of data: the\nfdarray and two fdsets.  The code allows the number of fds supported by the\nfdarray (fdtable-\u003emax_fds) to differ from the number of fds supported by each\nof the fdsets (fdtable-\u003emax_fdset).\n\nIn practice, it is wasteful for these two sizes to differ: whenever we hit a\nlimit on the smaller-capacity structure, we will reallocate the entire fdtable\nand all the dynamic arrays within it, so any delta in the memory used by the\nlarger-capacity structure will never be touched at all.\n\nRather than hogging this excess, we shouldn\u0027t even allocate it in the first\nplace, and keep the capacities of the fdarray and the fdsets equal.  This\npatch removes fdtable-\u003emax_fdset.

      "message": "[PATCH] Shrinks sizeof(files_struct) and better layout\n\n1) Reduce the size of (struct fdtable) to exactly 64 bytes on 32bits\n   platforms, lowering kmalloc() allocated space by 50%.\n\n2) Reduce the size of (files_struct), using a special 32 bits (or\n   64bits) embedded_fd_set, instead of a 1024 bits fd_set for the\n   close_on_exec_init and open_fds_init fields.  This save some ram (248\n   bytes per task) as most tasks dont open more than 32 files.  D-Cache\n   footprint for such tasks is also reduced to the minimum.\n\n3) Reduce size of allocated fdset.  Currently two full pages are\n   allocated, that is 32768 bits on x86 for example, and way too much.  The\n   minimum is now L1_CACHE_BYTES.\n\nUP and SMP should benefit from this patch, because most tasks will touch\nonly one cache line when open()/close() stdin/stdout/stderr (0/1/2),\n(next_fd, close_on_exec_init, open_fds_init, fd_array[0 ..  2] being in the\nsame cache line)\n\nSigned-off-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] files: files struct with RCU\n\nPatch to eliminate struct files_struct.file_lock spinlock on the reader side\nand use rcu refcounting rcuref_xxx api for the f_count refcounter.  The\nupdates to the fdtable are done by allocating a new fdtable structure and\nsetting files-\u003efdt to point to the new structure.  The fdtable structure is\nprotected by RCU thereby allowing lock-free lookup.  For fd arrays/sets that\nare vmalloced, we use keventd to free them since RCU callbacks can\u0027t sleep.  A\nglobal list of fdtable to be freed is not scalable, so we use a per-cpu list.\nIf keventd is already handling the current cpu\u0027s work, we use a timer to defer\nqueueing of that work.\n\nSince the last publication, this patch has been re-written to avoid using\nexplicit memory barriers and use rcu_assign_pointer(), rcu_dereference()\npremitives instead.  This required that the fd information is kept in a\nseparate structure (fdtable) and updated atomically.\n\nSigned-off-by: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
