Why?\nBecause when we have it like this, the 64-bit system calls now don\u0027t use\nthe \"pos_high\" argument at all, and it makes more sense for the native\nsystem call to simply match the user-mode prototype.\n\nThis results in a much more natural calling convention, and allows the\ncompiler to generate much more straightforward code. On x86-64, we now\ngenerate\n\n testq %rcx, %rcx # pos_l\n js .L122 #,\n movq %rcx, -48(%rbp) # pos_l, pos\n\nfrom the C source\n\n loff_t pos \u003d pos_from_hilo(pos_h, pos_l);\n\t...\n if (pos \u003c 0)\n return -EINVAL;\n\nand the \u0027pos_h\u0027 register isn\u0027t even touched. It used to generate code\nlike\n\n mov %r8d, %r8d # pos_low, pos_low\n salq $32, %rcx #, tmp71\n movq %r8, %rax # pos_low, pos.386\n orq %rcx, %rax # tmp71, pos.386\n js .L122 #,\n movq %rax, -48(%rbp) # pos.386, pos\n\nwhich isn\u0027t _that_ horrible, but it does show how the natural word size\nis just a more sensible interface (same arguments will hold in the user\nlevel glibc wrapper function, of course, so the kernel side is just half\nof the equation!)\n\nNote: in all cases the user code wrapper can again be the same. You can\njust do\n\n\t#define HALF_BITS (sizeof(unsigned long)*4)\n\t__syscall(PWRITEV, fd, iov, count, offset, (offset \u003e\u003e HALF_BITS) \u003e\u003e HALF_BITS);\n\nor something like that. That way the user mode wrapper will also be\nnicely passing in a zero (it won\u0027t actually have to do the shifts, the\ncompiler will understand what is going on) for the last argument.\n\nAnd that is a good idea, even if nobody will necessarily ever care: if\nwe ever do move to a 128-bit lloff_t, this particular system call might\nbe left alone. Of course, that will be the least of our worries if we\nreally ever need to care, so this may not be worth really caring about.\n\n[ Fixed for lost \u0027loff_t\u0027 cast noticed by Andrew Morton ]\n\nAcked-by: Gerd Hoffmann \u003ckraxel@redhat.com\u003e\nCc: H.

These have been discussed a lot on the LKML and\nCacheFS mailing lists, but to summarise the basics:\n\n (1) Most filesystems don\u0027t do hole reportage. Holes in files are treated as\n blocks of zeros and can\u0027t be distinguished otherwise, making it difficult\n to distinguish blocks that have been read from the network and cached from\n those that haven\u0027t.\n\n (2) The backing inode must be fully populated before being exposed to\n userspace through the main inode because the VM/VFS goes directly to the\n backing inode and does not interrogate the front inode\u0027s VM ops.\n\n Therefore:\n\n (a) The backing inode must fit entirely within the cache.\n\n (b) All backed files currently open must fit entirely within the cache at\n \t the same time.\n\n (c) A working set of files in total larger than the cache may not be\n \t cached.\n\n (d) A file may not grow larger than the available space in the cache.\n\n (e) A file that\u0027s open and cached, and remotely grows larger than the\n \t cache is potentially stuffed.\n\n (3) Writes go to the backing filesystem, and can only be transferred to the\n network when the file is closed.\n\n (4) There\u0027s no record of what changes have been made, so the whole file must\n be written back.\n\n (5) The pages belong to the backing filesystem, and all metadata associated\n with that page are relevant only to the backing filesystem, and not\n anything stacked atop it.\n\nOVERVIEW\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nFS-Cache provides (or will provide) the following facilities:\n\n (1) Caches can be added / removed at any time, even whilst in use.\n\n (2) Adds a facility by which tags can be used to refer to caches, even if\n they\u0027re not available yet.\n\n (3) More than one cache can be used at once. Caches can be selected\n explicitly by use of tags.\n\n (4) The netfs is provided with an interface that allows either party to\n withdraw caching facilities from a file (required for (1)).\n\n (5) A netfs may annotate cache objects that belongs to it. This permits the\n storage of coherency maintenance data.\n\n (6) Cache objects will be pinnable and space reservations will be possible.\n\n (7) The interface to the netfs returns as few errors as possible, preferring\n rather to let the netfs remain oblivious.\n\n (8) Cookies are used to represent indices, files and other objects to the\n netfs. The simplest cookie is just a NULL pointer - indicating nothing\n cached there.\n\n (9) The netfs is allowed to propose - dynamically - any index hierarchy it\n desires, though it must be aware that the index search function is\n recursive, stack space is limited, and indices can only be children of\n indices.\n\n(10) Indices can be used to group files together to reduce key size and to make\n group invalidation easier. The use of indices may make lookup quicker,\n but that\u0027s cache dependent.\n\n(11) Data I/O is effectively done directly to and from the netfs\u0027s pages. The\n netfs indicates that page A is at index B of the data-file represented by\n cookie C, and that it should be read or written. The cache backend may or\n may not start I/O on that page, but if it does, a netfs callback will be\n invoked to indicate completion. The I/O may be either synchronous or\n asynchronous.\n\n(12) Cookies can be \"retired\" upon release. At this point FS-Cache will mark\n them as obsolete and the index hierarchy rooted at that point will get\n recycled.\n\n(13) The netfs provides a \"match\" function for index searches. In addition to\n saying whether a match was made or not, this can also specify that an\n entry should be updated or deleted.\n\nFS-Cache maintains a virtual index tree in which all indices, files, objects\nand pages are kept. Bits of this tree may actually reside in one or more\ncaches.\n\n FSDEF\n |\n +------------------------------------+\n | |\n NFS AFS\n | |\n +--------------------------+ +-----------+\n | | | |\n homedir mirror afs.org redhat.com\n | | |\n +------------+ +---------------+ +----------+\n | | | | | |\n 00001 00002 00007 00125 vol00001 vol00002\n | | | | |\n +---+---+ +-----+ +---+ +------+------+ +-----+----+\n | | | | | | | | | | | | |\nPG0 PG1 PG2 PG0 XATTR PG0 PG1 DIRENT DIRENT DIRENT R/W R/O Bak\n | |\n PG0 +-------+\n | |\n 00001 00003\n |\n +---+---+\n | | |\n PG0 PG1 PG2\n\nIn the example above, two netfs\u0027s can be seen to be backed: NFS and AFS. These\nhave different index hierarchies:\n\n (*) The NFS primary index will probably contain per-server indices. Each\n server index is indexed by NFS file handles to get data file objects.\n Each data file objects can have an array of pages, but may also have\n further child objects, such as extended attributes and directory entries.\n Extended attribute objects themselves have page-array contents.\n\n (*) The AFS primary index contains per-cell indices. Each cell index contains\n per-logical-volume indices. Each of volume index contains up to three\n indices for the read-write, read-only and backup mirrors of those volumes.\n Each of these contains vnode data file objects, each of which contains an\n array of pages.\n\nThe very top index is the FS-Cache master index in which individual netfs\u0027s\nhave entries.\n\nAny index object may reside in more than one cache, provided it only has index\nchildren. Any index with non-index object children will be assumed to only\nreside in one cache.\n\nThe FS-Cache overview can be found in:\n\n\tDocumentation/filesystems/caching/fscache.txt\n\nThe netfs API to FS-Cache can be found in:\n\n\tDocumentation/filesystems/caching/netfs-api.txt\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Steve Dickson \u003csteved@redhat.com\u003e\nAcked-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nTested-by: Daire Byrne \u003cDaire.Byrne@framestore.com\u003e\n" }, { "commit": "266cf658efcf6ac33541a46740f74f50c79d2b6b", "tree": "5c83b0879892d509e598dfd54be3ba3679ecd348", "parents": [ "03fb3d2af96c2783c3a5bc03f3d984cf422f0e69" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Apr 03 16:42:36 2009 +0100" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Apr 03 16:42:36 2009 +0100" }, "message": "FS-Cache: Recruit a page flags for cache management\n\nRecruit a page flag to aid in cache management.
