This patch adds into write inode path function to write UFS2 inode, and modifys allocate inode path to allocate and init additional inode chunks. Also some cleanups: - remove not used parameters in some functions - remove i_gen field from ufs_inode_info structure, there is i_generation in inode structure with same purposes. Signed-off-by:

These series of patches add UFS2 write-support. UFS2 - is default file system for recent versions of FreeBSD. The main differences from UFS1 from write support point of view are: 1)Not all inodes are allocated during formatation of disk. 2)All meta-data(pointer to data blocks) are 64bit(in UFS1 they are 32bit). So patch series consist of 1)make possible mount UFS2 in read-write mode 2)code to write ufs2 inodes and code to initialize inodes chunks. 3)work with 64bit meta-data I made simple testing like create/deleting/writing/reading/truncating, also I ran fsx-linux and untar and build kernel on UFS1 and UFS2, after that FreeBSD fsck do not find any errors in fs. This patch makes possible to mount ufs2 "rw", and updates UFS2 documentation: remove note about bug(it fixed by reallocate blocks on the fly patch) and add me in the list of people who want receive bug reports.

Current implementation allows the kernel to receive up to 255 characters from the bootloader. While the boot protocol allows greater buffers to be sent. In current environment, the command-line is used in order to specify many values, including suspend/resume, module arguments, splash, initramfs and more. 255 characters are not enough anymore. After edd issue was fixed, and dynammic kernel command-line patch was accepted, we can extend the COMMAND_LINE_SIZE without runtime memory requirements. Signed-off-by:

Current implementation stores a static command-line buffer allocated to COMMAND_LINE_SIZE size. Most architectures stores two copies of this buffer, one for future reference and one for parameter parsing. Current kernel command-line size for most architecture is much too small for module parameters, video settings, initramfs paramters and much more. The problem is that setting COMMAND_LINE_SIZE to a grater value, allocates static buffers. In order to allow a greater command-line size, these buffers should be dynamically allocated or marked as init disposable buffers, so unused memory can be released. This patch renames the static saved_command_line variable into boot_command_line adding __initdata attribute, so that it can be disposed after initialization. This rename is required so applications that use saved_command_line will not be affected by this change. It reintroduces saved_command_line as dynamically allocated buffer to match the data in boot_command_line. It also mark secondary command-line buffer as __initdata, and copies it to dynamically allocated static_command_line buffer components may hold reference to it after initialization. This patch is for linux-2.6.20-rc4-mm1 and is divided to target each architecture. I could not check this in any architecture so please forgive me if I got it wrong. The per-architecture modification is very simple, use boot_command_line in place of saved_command_line. The common code is the change into dynamic command-line. This patch: 1. Rename saved_command_line into boot_command_line, mark as init disposable. 2. Add dynamic allocated saved_command_line. 3. Add dynamic allocated static_command_line. 4. During startup copy: boot_command_line into saved_command_line. arch command_line into static_command_line. 5. Parse static_command_line and not arch command_line, so arch command_line may be freed.

Avoid expensive integer divide 3 times per CPU per tick. A userspace test of this loop went from 26ns, down to 19ns on a G5; and from 123ns down to 28ns on a P3. (Also avoid a variable bit shift, as suggested by Alan. The effect of this wasn't noticable on the CPUs I tested with). Signed-off-by:

sys_write() takes a local copy of f_pos and writes that back into the struct file. It does this so that two concurrent write() callers don't make a mess of f_pos, and of the file contents. ecryptfs should be calling vfs_write(). That way we also get the fsnotify notifications, which ecryptfs presently appears to have subverted. Convert direct calls to f_op->write() into calls to vfs_write(). Signed-off-by:
