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). Patches for s390(x) and ia64 are already available from\n previous posts, but it was decided that they should be added later\n once fallocate is in the mainline. Hence not including those patches\n in this take.\n2. Changes to glibc,\n a) to support fallocate() system call\n b) to make posix_fallocate() and posix_fallocate64() call fallocate()\n\nSigned-off-by: Amit Arora \u003caarora@in.ibm.com\u003e\n" }, { "commit": "edd5cd4a9424f22b0fa08bef5e299d41befd5622", "tree": "dba461b19b066c862a2c4e443b2deb9443bc78c5", "parents": [ "2f4d4da8f82c2598b8713f4a01f360f3751d90be" ], "author": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Wed Jun 27 14:10:09 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Jun 28 11:38:30 2007 -0700" }, "message": "Introduce fixed sys_sync_file_range2() syscall, implement on PowerPC and ARM\n\nNot all the world is an i386. Many architectures need 64-bit arguments to be\naligned in suitable pairs of registers, and the original\nsys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an\nargument register for padding after the first integer. Since we don\u0027t\nnormally have more than 6 arguments for system calls, that left no room for\nthe final argument on some architectures.\n\nFix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which\nall fits nicely. In fact, ARM already had that, but called it\nsys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement\nthe needed compatibility routine. And stop the missing syscall check from\nbitching about the absence of sys_sync_file_range() if we\u0027ve implemented\nsys_sync_file_range2() instead.\n\nTested on PPC32 and with 32-bit and 64-bit
