There is no reason to write out the metadata inodes or volume headers during a non-blocking sync, as we are almost guaranteed to dirty them again during the inode writeouts. Signed-off-by: Christoph Hellwig <hch@tuxera.com>

hfsplus stores all metadata except for the volume headers in special inodes. While these are marked hashed and periodically written out by the flusher threads, we can't rely on that for sync. For the case of a data integrity sync the VM has life-lock avoidance code that avoids writing inodes again that are redirtied during the sync, which is something that can happen easily for hfsplus. So make sure we explicitly write out the metadata inodes at the beginning of hfsplus_sync_fs. Signed-off-by: Christoph Hellwig <hch@tuxera.com>

Switch the hfsplus partition table reding for cdroms to use our bio helpers. Again we don't rely on any caching in the buffer_heads, and this gets rid of the last buffer_head use in hfsplus. Signed-off-by: Christoph Hellwig <hch@tuxera.com>

The hfsplus backup volume header is located two blocks from the end of the device. In case of device sizes that are not 4k aligned this means we can't access it using buffer_heads when using the default 4k block size. Switch to using raw bios to read/write all buffer headers. We were not relying on any caching behaviour of the buffer heads anyway. Additionally always read in the backup volume header during mount to verify that we can actually read it.

Remove opencoded writing of the volume header in hfsplus_fill_super and hfsplus_put_super and offload it to hfsplus_sync_fs. In the put_super case this means we only write the superblock once instead of twice. Signed-off-by: Christoph Hellwig <hch@tuxera.com>

hfsplus only actually uses the force option during remount, but it uses the full option parser with a fake superblock to do so. This means remount will fail if any nls option is set (which happens frequently with older mount tools), even if it is the same. Fix this by adding a simpler version of the parser that only parses the force option for remount. Signed-off-by: Christoph Hellwig <hch@tuxera.com>

Linus noted, and complained to me, that doing while lots of "git diff"'s of kernel sources, these spinlocks were responsible for 27% of the spinlock cost on his two-processor system as reported by perf. Git was doing lots of parallel stats, and this was putting a lot of pressure on ext4_getattr(). A spinlock to protect a single memory-to-memory copy is pointless, so remove it.

This patch adds support for Power/Status LED on Creative USB X-Fi S51. There is just one LED on the device. The LED can either be On or it can be set to Blink. There doesn't seem to be a way to switch it off. The control message to change LED status is similar to that of audigy2nx except that the index is to be set to 0 and value is 1 for Blink and 0 for On. The 'Power LED' control in alsamixer when muted will cause the LED to Blink continuously. When unmuted the LED will stay On. The Creative driver under Windows sets the LED to blink whenever audio is muted. This LED can be treated as the CMSS LED but I figured since there is just one LED, it should be treated as the Power LED. Is that alright? I've also changed the comment "Usb X-Fi" to "Usb X-Fi S51" as there are other external X-Fi devices from Creative like Usb X-Fi Go and Xmod. The volume knob and LED support patch doesn't apply to them. Signed-off-by: Mandar Joshi <emailmandar@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

I noticed that sound/pci/asihpi/hpicmn.c::hpi_alloc_control_cache() does not check the return value from kmalloc(), which may fail. If kmalloc() fails we'll dereference a null pointer and things will go bad fast. There are two memory allocations in that function and there's also the problem that the first may succeed and the second may fail and nothing is done about that either which will also go wrong down the line.

Not all bits can be read back from POWER1 so avoid corruption when using a read/modify/write cycle by marking it non-volatile - the only thing we read back from it is the chip revision which has diagnostic value only. We can re-add later but that's a more invasive change than is suitable for a bugfix.

When reading through sound/pci/cs46xx/dsp_spos.c I noticed a couple of things in cs46xx_dsp_spos_create(). It seems to me that we don't always free the various memory buffers we allocate and we also do some work (structure member assignment) early, that is completely pointless if some of the memory allocations fail and we end up just aborting the whole thing. I don't have hardware to test, so the patch below is compile tested only, but it makes the following changes: - Make sure we always free all allocated memory on failures. - Don't do pointless work assigning to structure members before we know all memory allocations, that may abort progress, have completed successfully. - Remove some trailing whitespace.
