| * | ALSA: emu10k1 - delay the PCM interrupts (add pcm_irq_delay parameter)Jaroslav Kysela2010-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With some hardware combinations, the PCM interrupts are acknowledged before the period boundary from the emu10k1 chip. The midlevel PCM code gets confused and the playback stream is interrupted. It seems that the interrupt processing shift by 2 samples is enough to fix this issue. This default value does not harm other, non-affected hardware.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The update of ->recovery_offset in sync_sbs is appropriate even then external metadata is in use. However sync_sbs is only called when native metadata is used. So move that update in to the top of md_update_sb (which is the only caller of sync_sbs) before the test on ->external. This moves the update out of ->write_lock protection, but those fields only need ->reconfig_mutex protection which they still have. Also move the test on ->persistent up to where ->external is set as for metadata update purposes they are the same. Clear MD_CHANGE_DEVS and MD_CHANGE_CLEAN as they can only be confusing if ->external is set or ->persistent isn't. Finally move the update of ->utime down as it is only relevent (like the ->events update) for native metadata.

Use that information to locate the video device instead of a half-baked hunt for _BCL. This uncouples the detection of the number of backlight brightness levels on ThinkPads from the ACPI paths in vid_handle. With this change, the driver should be able to always detect whether the ThinkPad uses a 8-level or 16-level brightness scale even on newer models for which the vid_handle paths have not been updated yet. It will skip deactivated devices in the ACPI device tree, which is a change in behaviour. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Matthew Garrett <mjg@redhat.com>

| * | nilfs2: fix false warning saying one of two super blocks is brokenRyusuke Konishi2010-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After applying commit b2ac86e1, the following message got appeared after unclean shutdown: > NILFS warning: broken superblock. using spare superblock. This turns out to be a false message due to the change which updates two super blocks alternately. The secondary super block now can be selected if it's newer than the primary one. This kills the false warning by suppressing it if another super block is not actually broken. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
| * | nilfs2: fix list corruption after ifile creation failureRyusuke Konishi2010-08-15

When a concurrently mounted snapshot is unmounted or another new snapshot is mounted after that, this causes kernel oops as below: > BUG: unable to handle kernel NULL pointer dereference at (null) > IP: [<f83662ff>] nilfs_find_sbinfo+0x74/0xa4 [nilfs2] > *pde = 00000000 > Oops: 0000 [#1] SMP <snip> > Call Trace: > [<f835dc29>] ? nilfs_get_sb+0x165/0x532 [nilfs2] > [<c1173c87>] ? ida_get_new_above+0x16d/0x187 > [<c109a7f8>] ? alloc_vfsmnt+0x7e/0x10a > [<c1070790>] ? kstrdup+0x2c/0x40 > [<c1089041>] ? vfs_kern_mount+0x96/0x14e > [<c108913d>] ? do_kern_mount+0x32/0xbd > [<c109b331>] ? do_mount+0x642/0x6a1 > [<c101a415>] ? do_page_fault+0x0/0x2d1 > [<c1099c00>] ? copy_mount_options+0x80/0xe2 > [<c10705d8>] ? strndup_user+0x48/0x67 > [<c109b3f1>] ? sys_mount+0x61/0x90 > [<c10027cc>] ? sysenter_do_call+0x12/0x22 This fixes the problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We leak at least 32bits of kernel memory to user land in tc dump, because we dont init all fields (capab ?) of the dumped structure.

Disable again BH to avoid these lockdep warnings. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Diagnosed-by: David S.
