Also it is full integrated with adaptive readahead.\n\nIt is designed to be called on demand:\n\t- on a missing page, to do synchronous readahead\n\t- on a lookahead page, to do asynchronous readahead\n\nIn this way it eliminated the awkward workarounds for cache hit/miss,\nreadahead thrashing, retried read, and unaligned read. It also adopts the\ndata structure introduced by adaptive readahead, parameterizes readahead\npipelining with `lookahead_index\u0027, and reduces the current/ahead windows to\none single window.\n\nHEURISTICS\n\nThe logic deals with four cases:\n\n\t- sequential-next\n\t\tfound a consistent readahead window, so push it forward\n\n\t- random\n\t\tstandalone small read, so read as is\n\n\t- sequential-first\n\t\tcreate a new readahead window for a sequential/oversize request\n\n\t- lookahead-clueless\n\t\thit a lookahead page not associated with the readahead window,\n\t\tso create a new readahead window and ramp it up\n\nIn each case, three parameters are determined:\n\n\t- readahead index: where the next readahead begins\n\t- readahead size: how much to readahead\n\t- lookahead size: when to do the next readahead (for pipelining)\n\nBEHAVIORS\n\nThe old behaviors are maximally preserved for trivial sequential/random reads.\nNotable changes are:\n\n\t- It no longer imposes strict sequential checks.\n\t It might help some interleaved cases, and clustered random reads.\n\t It does introduce risks of a random lookahead hit triggering an\n\t unexpected readahead. But in general it is more likely to do good\n\t than to do evil.\n\n\t- Interleaved reads are supported in a minimal way.\n\t Their chances of being detected and proper handled are still low.\n\n\t- Readahead thrashings are better handled.\n\t The current readahead leads to tiny average I/O sizes, because it\n\t never turn back for the thrashed pages. They have to be fault in\n\t by do_generic_mapping_read() one by one. Whereas the on-demand\n\t readahead will redo readahead for them.\n\nOVERHEADS\n\nThe new code reduced the overheads of\n\n\t- excessively calling the readahead routine on small sized reads\n\t (the current readahead code insists on seeing all requests)\n\n\t- doing a lot of pointless page-cache lookups for small cached files\n\t (the current readahead only turns itself off after 256 cache hits,\n\t unfortunately most files are \u003c 1MB, so never see that chance)\n\nThat accounts for speedup of\n\t- 0.3% on 1-page sequential reads on sparse file\n\t- 1.2% on 1-page cache hot sequential reads\n\t- 3.2% on 256-page cache hot sequential reads\n\t- 1.3% on cache hot `tar /lib`\n\nHowever, it does introduce one extra page-cache lookup per cache miss, which\nimpacts random reads slightly. That\u0027s 1% overheads for 1-page random reads on\nsparse file.\n\nPERFORMANCE\n\nThe basic benchmark setup is\n\t- 2.6.20 kernel with on-demand readahead\n\t- 1MB max readahead size\n\t- 2.9GHz Intel Core 2 CPU\n\t- 2GB memory\n\t- 160G/8M Hitachi SATA II 7200 RPM disk\n\nThe benchmarks show that\n\t- it maintains the same performance for trivial sequential/random reads\n\t- sysbench/OLTP performance on MySQL gains up to 8%\n\t- performance on readahead thrashing gains up to 3 times\n\niozone throughput (KB/s): roughly the

Namely, in that cases we need\nto disable the GPEs before replacing the \"boot\" kernel with the \"frozen\"\nkernel (cf. http://bugzilla.kernel.org/show_bug.cgi?id\u003d7887). After the\nrestore they will be re-enabled by hibernation_ops-\u003efinish(), but if the\nrestore fails, they have to be re-enabled by the restore code explicitly.\n\nFor this purpose we can introduce two additional hibernation operations,\ncalled pre_restore() and restore_cleanup() and call them from the restore code\npath. Still, they should be called if the \"platform\" mode of hibernation has\nbeen used, so we need to pass the information about the hibernation mode from\nthe \"frozen\" kernel to the \"boot\" kernel in the image header.\n\nApparently, we can\u0027t drop the disabling of GPEs before the restore because of\nBug #7887 .  We also can\u0027t do it unconditionally, because the GPEs wouldn\u0027t\nhave been enabled after a successful restore if the suspend had been done in\nthe \u0027shutdown\u0027 or \u0027reboot\u0027 mode.\n\nIn principle we could (and probably should) unconditionally disable the GPEs\nbefore each snapshot creation *and* before the restore, but then we\u0027d have to\nunconditionally enable them after the snapshot creation as well as after the\nrestore (or restore failure)   Still, for this purpose we\u0027d need to modify\nacpi_enter_sleep_state_prep() and acpi_leave_sleep_state() and we\u0027d have to\nintroduce some mechanism synchronizing the disablind/enabling of the GPEs with\nthe device drivers\u0027 .suspend()/.resume() routines and with\ndisable_/enable_nonboot_cpus().  However, this would have affected the\nsuspend (ie. s2ram) code as well as the hibernation, which I\u0027d like to avoid\nin this patch series.\n\nSigned-off-by: Rafael J.

Between shooting down ptes to\na particular page, and actually dropping the struct page from the pagecache,\ndo_no_page from any process might fault on that page and establish a new\nmapping to the page just before it gets discarded from the pagecache.\n\nThe most common case where such invalidation is used is in file truncation.\nThis case was catered for by doing a sort of open-coded seqlock between the\nfile\u0027s i_size, and its truncate_count.\n\nTruncation will decrease i_size, then increment truncate_count before\nunmapping userspace pages; do_no_page will read truncate_count, then find the\npage if it is within i_size, and then check truncate_count under the page\ntable lock and back out and retry if it had subsequently been changed (ptl\nwill serialise against unmapping, and ensure a potentially updated\ntruncate_count is actually visible).\n\nComplexity and documentation issues aside, the locking protocol fails in the\ncase where we would like to invalidate pagecache inside i_size. do_no_page\ncan come in anytime and filemap_nopage is not aware of the invalidation in\nprogress (as it is when it is outside i_size). The end result is that\ndangling (-\u003emapping \u003d\u003d NULL) pages that appear to be from a particular file\nmay be mapped into userspace with nonsense data. Valid mappings to the same\nplace will see a different page.\n\nAndrea implemented two working fixes, one using a real seqlock, another using\na page-\u003eflags bit. He also proposed using the page lock in do_no_page, but\nthat was initially considered too heavyweight. However, it is not a global or\nper-file lock, and the page cacheline is modified in do_no_page to increment\n_count and _mapcount anyway, so a further modification should not be a large\nperformance hit. Scalability is not an issue.\n\nThis patch implements this latter approach. -\u003enopage implementations return\nwith the page locked if it is possible for their underlying file to be\ninvalidated (in that case, they must set a special vm_flags bit to indicate\nso). do_no_page only unlocks the page after setting up the mapping\ncompletely. invalidation is excluded because it holds the page lock during\ninvalidation of each page (and ensures that the page is not mapped while\nholding the lock).\n\nThis also allows significant simplifications in do_no_page, because we have\nthe page locked in the right place in the pagecache from the start.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus

This patch does not support block-mapped files currently.\nOnly FALLOC_ALLOCATE and FALLOC_RESV_SPACE modes are being supported as of\nnow.\n\nSigned-off-by: Amit Arora \u003caarora@in.ibm.com\u003e\n" }, { "commit": "97ac73506c0ba93f30239bb57b4cfc5d73e68a62", "tree": "4d02848d6c792a70b413deadcaffd7bf8c8d61de", "parents": [ "cb32da0416b823b7f4b65e7e85d6cba16ca4d1e1" ], "author": { "name": "Amit Arora", "email": "aarora@in.ibm.com", "time": "Tue Jul 17 21:42:44 2007 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Tue Jul 17 21:42:44 2007 -0400" }, "message": "sys_fallocate() implementation on i386, x86_64 and powerpc\n\nfallocate() is a new system call being proposed here which will allow\napplications to preallocate space to any file(s) in a file system.\nEach file system implementation that wants to use this feature will need\nto support an inode operation called -\u003efallocate().\nApplications can use this feature to avoid fragmentation to certain\nlevel and thus get faster access speed. With preallocation, applications\nalso get a guarantee of space for particular file(s) - even if later the\nthe system becomes full.\n\nCurrently, glibc provides an interface called posix_fallocate() which\ncan be used for similar cause. Though this has the advantage of working\non all file systems, but it is quite slow (since it writes zeroes to\neach block that has to be preallocated). Without a doubt, file systems\ncan do this more efficiently within the kernel, by implementing\nthe proposed fallocate() system call. It is expected that\nposix_fallocate() will be modified to call this new system call first\nand incase the kernel/filesystem does not implement it, it should fall\nback to the current implementation of writing zeroes to the new blocks.\nToDos:\n1. Implementation on other architectures (other than i386, x86_64,\n and ppc).
