| | | | | | | | | | | | | | | | The task_struct->pid member is going to be deprecated, so start using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in the kernel. The first thing to start with is the pid, printed to dmesg - in this case we may safely use task_pid_nr(). Besides, printks produce more (much more) than a half of all the explicit pid usage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix f_version type: should be u64 instead of long There is a type inconsistency between struct inode i_version and struct file f_version. fs.h: struct inode u64 i_version; and struct file unsigned long f_version; Users do: fs/ext3/dir.c: if (filp->f_version != inode->i_version) { So why isn't f_version a u64 ? It becomes a problem if versions gets higher than 2^32 and we are on an architecture where longs are 32 bits. This patch changes the f_version type to u64, and updates the users accordingly.

Inode size field reflects the actual amount of inline data available, which makes searching for dirent space very similar to the regular directory search.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes up write, truncate, mmap, and RESVSP/UNRESVP to understand inline inode data. For the most part, the changes to the core write code can be relied on to do the heavy lifting. Any code calling ocfs2_write_begin (including shared writeable mmap) can count on it doing the right thing with respect to growing inline data to an extent tree. Size reducing truncates, including UNRESVP can simply zero that portion of the inode block being removed. Size increasing truncatesm, including RESVP have to be a little bit smarter and grow the inode to an extent tree if necessary.

* ocfs2: Allow smaller allocations during large writesMark Fasheh2007-09-215-14/+36
| | | | | | | | | | | | | | | | | | | | | | | | The ocfs2 write code loops through a page much like the block code, except that ocfs2 allocation units can be any size, including larger than page size. Typically it's equal to or larger than page size - most kernels run 4k pages, the minimum ocfs2 allocation (cluster) size. Some changes introduced during 2.6.23 changed the way writes to pages are handled, and inadvertantly broke support for > 4k page size. Instead of just writing one cluster at a time, we now handle the whole page in one pass. This means that multiple (small) seperate allocations might happen in the same pass. The allocation code howver typically optimizes by getting the maximum which was reserved. This triggered a BUG_ON in the extend code where it'd ask for a single bit (for one part of a > 4k page) and get back more than it asked for. Fix this by providing a variant of the high level allocation function which allows the caller to specify a maximum. The traditional function remains and just calls the new one with a maximum determined from the initial reservation. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
