2009-01-05ocfs2/xattr: Only set buffer update if it doesn't exist in cache.Tao Ma
When we call ocfs2_init_xattr_bucket, we deem that the new buffer head will be written to disk immediately, so we just use sb_getblk. But in some cases the buffer may have already been in ocfs2 uptodate cache, so we only call ocfs2_set_buffer_uptodate if the buffer head isn't in the cache.

2009-01-05ocfs2/xattr: Remove additional bucket allocation in bucket defragment.Tao Ma
Joel has refactored xattr bucket and make xattr bucket a general wrapper. So in ocfs2_defrag_xattr_bucket, we have already passed the bucket in, so there is no need to allocate a new one and read it.

2009-01-05ocfs2: Use buckets in ocfs2_xattr_set_entry_in_bucket().Joel Becker

2009-01-05ocfs2: Use buckets in ocfs2_xattr_create_index_block().Joel Becker
Use the ocfs2_xattr_bucket abstraction in ocfs2_xattr_create_index_block() and its helpers. We get more efficient reads, a lot less buffer_head munging, and nicer code to boot. While we're at it, ocfs2_xattr_update_xattr_search() becomes void. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2009-01-05ocfs2: Use buckets in ocfs2_xattr_bucket_find().Joel Becker
Change the ocfs2_xattr_bucket_find() function to use ocfs2_xattr_bucket as its abstraction. This makes for more efficient reads, as buckets are linear blocks, and also has improved caching characteristics. It also reads better.

2009-01-05ocfs2: Take ocfs2_xattr_bucket structures off of the stack.Joel Becker
The ocfs2_xattr_bucket structure is a nice abstraction, but it is a bit large to have on the stack. Just like ocfs2_path, let's allocate it with a ocfs2_xattr_bucket_new() function. We can now store the inode on the bucket, cleaning up all the other bucket functions. While we're here, we catch another place or two that wasn't using ocfs2_read_xattr_bucket(). Updates: - No longer allocating xis.bucket, as it will never be used. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2009-01-05ocfs2: Copy xattr buckets with a dedicated function.Joel Becker

2009-01-05ocfs2: Wrap journal_access/journal_dirty for xattr buckets.Joel Becker
A common action is to call ocfs2_journal_access() and ocfs2_journal_dirty() on the buffer heads of an xattr bucket. Let's create nice wrappers. While we're there, let's drop the places that try to be smart by writing only the first and last blocks of a bucket. A bucket is contiguous, so writing the whole thing is actually more efficient.

2009-01-05ocfs2: Improve ocfs2_read_xattr_bucket().Joel Becker
The ocfs2_read_xattr_bucket() function would read an xattr bucket into a list of buffer heads. However, we have a nice ocfs2_xattr_bucket structure. Let's have it fill that out instead. In addition, ocfs2_read_xattr_bucket() would initialize buffer heads for a bucket that's never been on disk before. That's confusing. Let's call that functionality ocfs2_init_xattr_bucket(). The functions ocfs2_cp_xattr_bucket() and ocfs2_half_xattr_bucket() are updated to use the ocfs2_xattr_bucket structure rather than raw bh lists. That way they can use the new read/init calls. In addition, they drop the wasted read of an existing target bucket. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2009-01-05ocfs2: Provide a wrapper to brelse() xattr bucket buffers.Joel Becker

2009-01-05ocfs2: Convenient access to an xattr bucket's header.Joel Becker
The xattr code often wants to access the ocfs2_xattr_header at the start of an bucket. Rather than walk the pointer chains, let's just create another nice macro. As a side benefit, we can get rid of the mostly spurious ->bu_xh element on the bucket structure. The idea is ripped from the ocfs2_path code.

2009-01-05ocfs2: Convenient access to xattr bucket data blocks.Joel Becker
The xattr code often wants to access the data pointer for blocks in an xattr bucket. This is usually found by dereferencing the bh array hanging off of the ocfs2_xattr_bucket structure.

2009-01-04fs: symlink write_begin allocation context fixNick Piggin
With the write_begin/write_end aops, page_symlink was broken because it could no longer pass a GFP_NOFS type mask into the point where the allocations happened. They are done in write_begin, which would always assume that the filesystem can be entered from reclaim. This bug could cause filesystem deadlocks. The funny thing with having a gfp_t mask there is that it doesn't really allow the caller to arbitrarily tinker with the context in which it can be called. It couldn't ever be GFP_ATOMIC, for example, because it needs to take the page lock. The only thing any callers care about is __GFP_FS anyway, so turn that into a single flag. Add a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on this flag in their write_begin function. Change __grab_cache_page to accept a nofs argument as well, to honour that flag (while we're there, change the name to grab_cache_page_write_begin which is more instructive and does away with random leading underscores). This is really a more flexible way to go in the end anyway -- if a filesystem happens to want any extra allocations aside from the pagecache ones in ints write_begin function, it may now use GFP_KERNEL (rather than GFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a random example).

2009-01-04viafb: fix crashes due to 4k stack overflowBruno Prémont
The function viafb_cursor() uses 2 stack-variables of CURSOR_SIZE bits; CURSOR_SIZE is defined as (8 * 1024). Using up twice 1k on stack is too much for 4k-stack (though it works with 8k-stacks). Make those two variables kzalloc'ed to preserve stack space. Also merge the whole lot of local struct's in viafb_ioctl into a union so the stack usage gets minimized here as well. (struct's are only accessed in their indicidual IOCTL case) This second part is only compile-tested as I know of no userspace app using the IOCTLs.

2009-01-03Make %p print '(null)' for NULL pointersLinus Torvalds
Before, when we only ever printed out the pointer value itself, a NULL pointer would never cause issues and might as well be printed out as just its numeric value. However, with the extended %p formats, especially %pR, we might validly want to print out resources for debugging. And sometimes they don't even exist, and the resource pointer is just NULL. Print it out as such, rather than oopsing. This is a more generic version of a patch done by Trent Piepho (catching all %p cases rather than just %pR, and using "(null)" instead of "[NULL]" to match glibc).

2009-01-03sanitize ifdefs in binfmt_aoutAl Viro
They are actually alpha vs. i386/arm/m68k i.e. ecoff vs. aout. In the only place where we actually tried to handle arm and i386/m68k in different ways (START_DATA() in coredump handling), the arm variant works for all of them (i386 and m68k have u.start_code set to 0).
