Patches have been now rebased to 2.6.22-rc1 kernel. Earlier they were based on 2.6.21. 2. An unnecessary export of symbol is removed from the ext4 preallocate patch. Details in the corresponding post (PATCH 4/5). 3. Return type now described in the interface description below. 4. Besides above points, everything is exactly same as TAKE2. -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ This is the new set of patches which take care of the review comments received from the community (mainly from Andrew). Description: ----------- fallocate() is a new system call being proposed here which will allow applications to preallocate space to any file(s) in a file system. Each file system implementation that wants to use this feature will need to support an inode operation called fallocate. Applications can use this feature to avoid fragmentation to certain level and thus get faster access speed. With preallocation, applications also get a guarantee of space for particular file(s) - even if later the the system becomes full. Currently, glibc provides an interface called posix_fallocate() which can be used for similar cause. Though this has the advantage of working on all file systems, but it is quite slow (since it writes zeroes to each block that has to be preallocated). Without a doubt, file systems can do this more efficiently within the kernel, by implementing the proposed fallocate() system call. It is expected that posix_fallocate() will be modified to call this new system call first and incase the kernel/filesystem does not implement it, it should fall back to the current implementation of writing zeroes to the new blocks. Interface: --------- The proposed system call's layout is: asmlinkage long sys_fallocate(int fd, int mode, loff_t offset, loff_t len) fd: The descriptor of the open file. mode*: This specifies the behavior of the system call. Currently the system call supports two modes - FA_ALLOCATE and FA_DEALLOCATE. FA_ALLOCATE: Applications can use this mode to preallocate blocks to a given file (specified by fd). This mode changes the file size if the preallocation is done beyond the EOF. It also updates the ctime/mtime in the inode of the corresponding file, marking a successfull allocation. FA_DEALLOCATE: This mode can be used by applications to deallocate the previously preallocated blocks. This also may change the file size and the ctime/mtime. * New modes might get added in future. One such new mode which is already under discussion is FA_PREALLOCATE, which when used will preallocate space but will not change the filesize and [cm]time. Since the semantics of this new mode is not clear and agreed upon yet, this patchset does not implement it currently. offset: This is the offset in bytes, from where the preallocation should start. len: This is the number of bytes requested for preallocation (from offset). RETURN VALUE: The system call returns 0 on success and an error on failure. This is done to keep the semantics same as of posix_fallocate(). sys_fallocate() on s390: ----------------------- There is a problem with s390 ABI to implement sys_fallocate() with the proposed order of arguments. Martin Schwidefsky has suggested a patch to solve this problem which makes use of a wrapper in the kernel. This will require special handling of this system call on s390 in glibc as well. But, this seems to be the best solution so far. Known Problem: ------------- mmapped writes into uninitialized extents is a known problem with the current ext4 patches. Like XFS, ext4 may need to implement ->page_mkwrite() to solve this. See: http://lkml.org/lkml/2007/5/8/583 Since there is a talk of ->fault() replacing ->page_mkwrite() and also with a generic block_page_mkwrite() implementation already posted, we can implement this later some time. See: http://lkml.org/lkml/2007/3/7/161 http://lkml.org/lkml/2007/3/18/198 ToDos: ----- 1> Implementation on other architectures (other than i386, x86_64, ppc64 and s390(x)). David Chinner has already posted a patch for ia64. 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() Changelog: --------- Each post will have an individual changelog for a particular patch.
