2013-02-05ALSA: hda - detect jacks on VT1708 even when no streams are activeDavid Henningsson
These days, GUIs such as Gnome sound settings want to be able to show the correct jack status even when no streams are currently running. I doubt this gives any measurable difference in power, but if it does, the "Jack Detect" control can still be used to turn polling off.

2013-02-04ALSA: hda - Fix default multichannel HDMI mapping regressionAnssi Hannula
Commit d45e6889ee69456a4d5b1bbb32252f460cd48fa9 ("ALSA: hda - Provide the proper channel mapping for generic HDMI driver") added support for custom channel maps in the HDA HDMI driver. Due to a mistake in an 'if' condition the custom map is always used even when no such map has been set. This causes incorrect channel mapping for multichannel audio by default. Pass per_pin->chmap_set to hdmi_setup_channel_mapping() as a parameter so that it can use it for detecting if a custom map has been set instead of checking if map is NULL (which is never the case).

For non-snoop mode, we fiddle with the page attributes of CORB/RIRB and the position buffer, but also the ring buffers.

2013-01-25ALSA: Make snd_printd() and snd_printdd() inlineTakashi Iwai
Because currently snd_printd() and snd_printdd() macros are expanded to empty when CONFIG_SND_DEBUG=n, a compile warning like below appears sometimes, and we had to covert it by ugly ifdefs: sound/pci/hda/patch_sigmatel.c: In function ‘stac92hd71bxx_fixup_hp’: sound/pci/hda/patch_sigmatel.c:2434:24: warning: unused variable ‘spec’ [-Wunused-variable] For "fixing" these issues better, this patch replaces snd_printd() and snd_printdd() definitions with empty inline functions instead of macros. This should have the same effect but shut up warnings like above. But since we had already put ifdefs, changing to inline functions would trigger compile errors. So, such ifdefs is removed in this patch. In addition, snd_pci_quirk name field is defined only when CONFIG_SND_DEBUG_VERBOSE is set, and the reference to it in snd_printdd() argument triggers the build errors, too. For avoiding these errors, introduce a new macro snd_pci_quirk_name() that is defined no matter how the debug option is set.

2013-01-24Btrfs: fix repeated delalloc work allocationMiao Xie
btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/ btrfs_queue_worker for this inode, and then it locks the list, checks the head of the list again. But because we don't delete the first inode that it deals with before, it will fetch the same inode. As a result, this function allocates a huge amount of btrfs_delalloc_work structures, and OOM happens. Fix this problem by splice this delalloc list.

First, though the current transaction->aborted check can stop the commit early and avoid unnecessary operations, it is too early, and some transaction handles don't end, those handles may set transaction->aborted after the check. Second, when we commit the transaction, we will wake up some worker threads to flush the space cache and inode cache. Those threads also allocate some transaction handles and may set transaction->aborted if some serious error happens. So we need more check for ->aborted when committing the transaction. Fix it.

2013-01-24Btrfs: put csums on the right ordered extentJosef Bacik
I noticed a WARN_ON going off when adding csums because we were going over the amount of csum bytes that should have been allowed for an ordered extent. This is a leftover from when we used to hold the csums privately for direct io, but now we use the normal ordered sum stuff so we need to make sure and check if we've moved on to another extent so that the csums are added to the right extent. Without this we could end up with csums for bytenrs that don't have extents to cover them yet. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

2013-01-24Btrfs: fix panic when recovering tree logJosef Bacik
A user reported a BUG_ON(ret) that occured during tree log replay. Ret was -EAGAIN, so what I think happened is that we removed an extent that covered a bitmap entry and an extent entry. We remove the part from the bitmap and return -EAGAIN and then search for the next piece we want to remove, which happens to be an entire extent entry, so we just free the sucker and return. The problem is ret is still set to -EAGAIN so we trip the BUG_ON(). The user used btrfs-zero-log so I'm not 100% sure this is what happened so I've added a WARN_ON() to catch the other possibility.
