This is the latest fallocate patchset and is rebased to 2.6.22. Following are the changes from TAKE5: 1) Rebased to 2.6.22 2) Added compat wrapper for x86_64 3) Dropped s390 and ia64 patches, since the platform maintaners can add the support for fallocate once it is in mainline. 4) Added a change suggested by Andreas for better extent-to-group alignment in ext4 (Patch 6/6). Please refer following post: http://www.mail-archive.com/linux-ext4@xxxxxxxxxxxxxxx/msg02445.html 5) Renamed mode flags and values from "FA_" to "FALLOC_" 6) Added manpage (updated version of the one initially submitted by David Chinner). Todos: ----- 1> Implementation on other architectures (other than i386, x86_64, and ppc64). s390(x) and ia64 patches are ready and will be pushed by platform maintaners when the fallocate is in mainline. 2> A generic file system operation to handle fallocate (generic_fallocate), for filesystems that do _not_ have the fallocate inode operation implemented. 3> Changes to glibc, a) to support fallocate() system call b) to make posix_fallocate() and posix_fallocate64() call fallocate() 4> A testcase to test the system call. Will post it soon. Following patches follow: Patch 1/7 : manpage for fallocate Patch 2/7 : fallocate() implementation in i386, x86_64 and powerpc Patch 3/7 : support new modes in fallocate Patch 4/7 : ext4: fallocate support in ext4 Patch 5/7 : ext4: write support for preallocated blocks Patch 6/7 : ext4: support new modes in ext4 Patch 7/7 : ext4: change for better extent-to-group alignment -- Regards, Amit Arora - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
