2009-09-27const: mark struct vm_struct_operationsAlexey Dobriyan1-1/+1
* mark struct vm_area_struct::vm_ops as const * mark vm_ops in AGP code But leave TTM code alone, something is fishy there with global vm_ops being used. Signed-off-by: Alexey Dobriyan <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2009-09-14ext4: Remove syncing logic from ext4_file_writeJan Kara1-51/+2
The syncing is now properly handled by generic_file_aio_write() so no special ext4 code is needed. CC: [email protected] CC: [email protected] Signed-off-by: Jan Kara <[email protected]>
2009-09-08ext[234]: move over to 'check_acl' permission modelLinus Torvalds1-1/+1
Don't implement per-filesystem 'extX_permission()' functions that have to be called for every path component operation, and instead just expose the actual ACL checking so that the VFS layer can now do it for us.

2009-06-13ext4: update the s_last_mounted field in the superblockTheodore Ts'o1-1/+35
This field can be very helpful when a system administrator is trying to sort through large numbers of block devices or filesystem images. What is stored in this field can be ambiguous if multiple filesystem namespaces are in play; what we store in practice is the mountpoint interpreted by the process's namespace which first opens a file in the filesystem.

2009-03-27ext4: Fix discard of inode prealloc space with delayed allocation.Aneesh Kumar K.V1-1/+2
With delayed allocation we should not/cannot discard inode prealloc space during file close. We would still have dirty pages for which we haven't allocated blocks yet. With this fix after each get_blocks request we check whether we have zero reserved blocks and if yes and we don't have any writers on the file we discard inode prealloc space.

2009-02-24ext4: Automatically allocate delay allocated blocks on closeTheodore Ts'o1-0/+4
When closing a file that had been previously truncated, force any delay allocated blocks that to be allocated so that if the filesystem is mounted with data=ordered, the data blocks will be pushed out to disk along with the journal commit. Many application programs expect this, so we do this to avoid zero length files if the system crashes unexpectedly. Signed-off-by: "Theodore Ts'o" <[email protected]>

2008-10-10ext4: Rename ext4dev to ext4Theodore Ts'o1-1/+1
The ext4 filesystem is getting stable enough that it's time to drop the "dev" prefix. Also remove the requirement for the TEST_FILESYS flag. Signed-off-by: "Theodore Ts'o" <[email protected]>
2008-10-07Hook ext4 to the vfs fiemap interface.Eric Sandeen1-0/+4
ext4_ext_walk_space() was reinstated to be used for iterating over file extents with a callback; it is used by the ext4 fiemap implementation. Signed-off-by: Eric Sandeen <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]> Cc: [email protected] Cc: [email protected]

2008-07-11ext4: delayed allocation i_blocks fix for statMingming Cao1-0/+1
Right now i_blocks is not getting updated until the blocks are actually allocaed on disk. This means with delayed allocation, right after files are copied, "ls -sF" shoes the file as taking 0 blocks on disk. "du" also shows the files taking zero space, which is highly confusing to the user. Since delayed allocation already keeps track of per-inode total number of blocks that are subject to delayed allocation, this patch fix this by using that to adjust the value returned by stat(2). When real block allocation is done, the i_blocks will get updated. Since the reserved blocks for delayed allocation will be decreased, this will be keep value returned by stat(2) consistent.

2008-07-11ext4: Use page_mkwrite vma_operations to get mmap write notification.Aneesh Kumar K.V1-1/+18
We would like to get notified when we are doing a write on mmap section. This is needed with respect to preallocated area. We split the preallocated area into initialzed extent and uninitialzed extent in the call back. This let us handle ENOSPC better. Otherwise we get ENOSPC in the writepage and that would result in data loss. The changes are also needed to handle ENOSPC when writing to an mmap section of files with holes.

2008-01-28ext4: Convert truncate_mutex to read write semaphore.Aneesh Kumar K.V1-2/+2
We are currently taking the truncate_mutex for every read. This would have performance impact on large CPU configuration. Convert the lock to read write semaphore and take read lock when we are trying to read the file. Signed-off-by: Aneesh Kumar K.V <[email protected]>
2008-01-28ext4: store maxbytes for bitmapped files and return EFBIG as appropriateEric Sandeen1-1/+18

2007-07-17fallocate support in ext4Amit Arora1-0/+1
This patch implements ->fallocate() inode operation in ext4. With this patch users of ext4 file systems will be able to use fallocate() system call for persistent preallocation. Current implementation only supports preallocation for regular files (directories not supported as of date) with extent maps. This patch does not support block-mapped files currently. Only FALLOC_ALLOCATE and FALLOC_RESV_SPACE modes are being supported as of now. Signed-off-by: Amit Arora <[email protected]>
2007-07-10sendfile: remove .sendfile from filesystems that use generic_file_sendfile()Jens Axboe1-1/+0
They can use generic_file_splice_read() instead. Since sys_sendfile() now prefers that, there should be no change in behaviour. Signed-off-by: Jens Axboe <[email protected]>
2007-02-12[PATCH] mark struct inode_operations const 1Arjan van de Ven1-1/+1
Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.
