These syscalls are a\npretty straightforward combination of pread and readv (same for write).\nThey are quite useful for doing vectored I/O in threaded applications.\nUsing lseek+readv instead opens race windows you\u0027ll have to plug with\nlocking.\n\nOther systems have such system calls too, for example NetBSD, check\nhere: http://www.daemon-systems.org/man/preadv.2.html\n\nThe application-visible interface provided by glibc should look like\nthis to be compatible to the existing implementations in the *BSD family:\n\n ssize_t preadv(int d, const struct iovec *iov, int iovcnt, off_t offset);\n ssize_t pwritev(int d, const struct iovec *iov, int iovcnt, off_t offset);\n\nThis prototype has one problem though: On 32bit archs is the (64bit)\noffset argument unaligned, which the syscall ABI of several archs doesn\u0027t\nallow to do. At least s390 needs a wrapper in glibc to handle this. As\nwe\u0027ll need a wrappers in glibc anyway I\u0027ve decided to push problem to\nglibc entriely and use a syscall prototype which works without\narch-specific wrappers inside the kernel: The offset argument is\nexplicitly splitted into two 32bit values.\n\nThe patch sports the actual system call implementation and the windup in\nthe x86 system call tables.

A sigbus is wrong for the case that the page has been\ninvalidated or truncated within i_size (eg. hole punched). Callers may\nalso have to perform memory allocations in this path, where again, SIGBUS\nwould be wrong.\n\nThe previous patch (\"mm: page_mkwrite change prototype to match fault\")\nmade it possible to properly specify errors. Convert the generic buffer.c\ncode and btrfs to return sane error values (in the case of page removed\nfrom pagecache, VM_FAULT_NOPAGE will cause the fault handler to exit\nwithout doing anything, and the fault will be retried properly).\n\nThis fixes core code, and converts btrfs as a template/example. All other\nfilesystems defining their own page_mkwrite should be fixed in a similar\nmanner.\n\nAcked-by: Chris Mason \u003cchris.mason@oracle.com\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c2ec175c39f62949438354f603f4aa170846aabb", "tree": "f2c9bf1bec2deabe2d3a5092405b027637b6ead3", "parents": [ "c2fdf3a9b2d52842808a8e551b53b55dd9b45030" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Tue Mar 31 15:23:21 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 01 08:59:14 2009 -0700" }, "message": "mm: page_mkwrite change prototype to match fault\n\nChange the page_mkwrite prototype to take a struct vm_fault, and return\nVM_FAULT_xxx flags.

The filesystem can make an effort to make sure the new data is\non disk before actually replacing the old data.\n\nThis is especially important for rename, which many application use as\nthough it were atomic for both the data and the metadata involved. The\ncurrent btrfs code will happily replace a file that is fully on disk\nwith one that was just created and still has pending IO.\n\nIf we crash after transaction commit but before the IO is done, we\u0027ll end\nup replacing a good file with a zero length file. The solution used\nhere is to create a list of inodes that need special ordering and force\nthem to disk before the commit is done. This is similar to the\next3 style data\u003dordering, except it is only done on selected files.\n\nBtrfs is able to get away with this because it does not wait on commits\nvery often, even for fsync (which use a sub-commit).\n\nFor renames, we order the file when it wasn\u0027t already\non disk and when it is replacing an existing file. Larger files\nare sent to filemap_flush right away (before the transaction handle is\nopened).\n\nFor truncates, we order if the file goes from non-zero size down to\nzero size. This is a little different, because at the time of the\ntruncate the file has no dirty bytes to order. But, we flag the inode\nso that it is added to the ordered list on close (via release method). We\nalso immediately add it to the ordered list of the current transaction\nso that we can try to flush down any writes the application sneaks in\nbefore commit.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "bff61975b3d6c18ee31457cc5b4d73042f44915f", "tree": "3aff48088b35172e74f56ae54f0b53e76a0c2150", "parents": [ "92022950c6b1bb3da90b2976b20271cdfd98b8a3" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Tue Mar 31 14:33:13 2009 +1100" }, "committer": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Tue Mar 31 14:33:13 2009 +1100" }, "message": "md: move lots of #include lines out of .h files and into .c\n\nThis makes the includes more explicit, and is preparation for moving\nmd_k.h to drivers/md/md.h\n\nRemove include/raid/md.h as its only remaining use was to #include\nother files.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\n" }, { "commit": "d17abcd5417d84cfa8a225160481203a37dc81d4", "tree": "74ce2c425c5c6550acec90bc92c8a3f735f0d257", "parents": [ "db6f204019380c788f1de06ee937bdbccd60e5c0", "bb75efddeaca89f8a67fd82cdcbaaf436cf17ca9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 30 18:00:26 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 30 18:00:26 2009 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-cpumask\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-cpumask:\n oprofile: Thou shalt not call __exit functions from __init functions\n cpumask: remove the now-obsoleted pcibus_to_cpumask(): generic\n cpumask: remove cpumask_t from core\n cpumask: convert rcutorture.c\n cpumask: use new cpumask_ functions in core code.\n cpumask: remove references to struct irqaction\u0027s mask field.\n cpumask: use mm_cpumask() wrapper: kernel/fork.c\n cpumask: use set_cpu_active in init/main.c\n cpumask: remove node_to_first_cpu\n cpumask: fix seq_bitmap_*() functions.\n cpumask: remove dangerous CPU_MASK_ALL_PTR, \u0026CPU_MASK_ALL\n" } ], "next": "cf2f7d7c90279cdbc12429de278f3d27ac2050ae" }
