2008-04-17udf: move headers out include/linux/Christoph Hellwig
There's really no reason to keep udf headers in include/linux as they're not used by anything but fs/udf/. This patch merges most of include/linux/udf_fs_i.h into fs/udf/udf_i.h, include/linux/udf_fs_sb.h into fs/udf/udf_sb.h and include/linux/udf_fs.h into fs/udf/udfdecl.h. The only thing remaining in include/linux/ is a stub of udf_fs_i.h defining the four user-visible udf ioctls. It's also moved from unifdef-y to headers-y because it can be included unconditionally now. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>
2008-04-17udf: kill useless file header comments for vfs method implementationsChristoph Hellwig
There's not need to document vfs method invocation rules, we have Documentation/filesystems/vfs.txt and Documentation/filesystems/Locking for that.

2008-02-08udf: fix adding entry to a directoryJan Kara
When adding directory entry to a directory, we have to properly increase length of the last extent. Handle this similarly as extending regular files - make extents always have size multiple of block size (it will be truncated down to proper size in udf_clear_inode()).

2008-02-08udf: cleanup directory offset handlingJan Kara
Position in directory returned by readdir is offset of directory entry divided by four (don't ask me why). Make this conversion only when reading f_pos from userspace / writing it there and internally work in bytes. It makes things more easily readable and also fixes a bug (we forgot to divide length of the entry by 4 when advancing f_pos in udf_add_entry()).

2007-06-16udf: fix possible leakage of blocksJan Kara
We have to take care that when we call udf_discard_prealloc() from udf_clear_inode() we have to write inode ourselves afterwards (otherwise, some changes might be lost leading to leakage of blocks, use of free blocks or improperly aligned extents). Also udf_discard_prealloc() does two different things - it removes preallocated blocks and truncates the last extent to exactly match i_size. We move the latter functionality to udf_truncate_tail_extent(), call udf_discard_prealloc() when last reference to a file is dropped and call udf_truncate_tail_extent() when inode is being removed from inode cache (udf_clear_inode() call). We cannot call udf_truncate_tail_extent() earlier as subsequent open+write would find the last block of the file mapped and happily write to the end of it, although the last extent says it's shorter.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

2007-05-08udf: support files larger than 1GJan Kara
Make UDF work correctly for files larger than 1GB. As no extent can be longer than (1<<30)-blocksize bytes, we have to create several extents if a big hole is being created. As a side-effect, we now don't discard preallocated blocks when creating a hole.
