2011-06-05ARM: Tegra: Harmony: Fix conflicting GPIO numberingStephen Warren2-2/+5
Currently, both the WM8903 and TPS6586x chips attempt to register with gpiolib using the same GPIO numbers. This causes the audio driver to fail to initialize. To solve this, add a define to board-harmony.h for the TPS6586x, and make board-harmony-power.c use this define, instead of directly referencing TEGRA_NR_GPIOS. This fixes a regression introduced by commit 6f168f2fa60f87e85e0df25e87e2372f22f5eb7c.

2011-06-04Btrfs: don't save the inode cache if we are deleting this rootJosef Bacik1-0/+5
With xfstest 254 I can panic the box every time with the inode number caching stuff on. This is because we clean the inodes out when we delete the subvolume, but then we write out the inode cache which adds an inode to the subvolume inode tree, and then when it gets evicted again the root gets added back on the dead roots list and is deleted again, so we have a double free. To stop this from happening just return 0 if refs is 0 (and we're not the tree root since tree root always has refs of 0). With this fix 254 no longer panics.

The current scrub implementation reuses bios and pages as often as possible, allocating them only on start and releasing them when finished.

This patch completely rips out the reuse of bios and pages and allocates them freshly for each submit.

2011-06-04more conservative S_NOSEC handlingAl Viro6-5/+8
Caching "we have already removed suid/caps" was overenthusiastic as merged. On network filesystems we might have had suid/caps set on another client, silently picked by this client on revalidate, all of that *without* clearing the S_NOSEC flag. AFAICS, the only reasonably sane way to deal with that is * new superblock flag; unless set, S_NOSEC is not going to be set. * local block filesystems set it in their ->mount() (more accurately, mount_bdev() does, so does btrfs ->mount(), users of mount_bdev() other than local block ones clear it) * if any network filesystem (or a cluster one) wants to use S_NOSEC, it'll need to set MS_NOSEC in sb->s_flags *AND* take care to clear S_NOSEC when inode attribute changes are picked from other clients. It's not an earth-shattering hole (anybody that can set suid on another client will almost certainly be able to write to the file before doing that anyway), but it's a bug that needs fixing.

2011-06-04Revert "tty: make receive_buf() return the amout of bytes received"Linus Torvalds20-128/+115
This reverts commit b1c43f82c5aa265442f82dba31ce985ebb7aa71c. It was broken in so many ways, and results in random odd pty issues. It re-introduced the buggy schedule_work() in flush_to_ldisc() that can cause endless work-loops (see commit a5660b41af6a: "tty: fix endless work loop when the buffer fills up"). It also used an "unsigned int" return value fo the ->receive_buf() function, but then made multiple functions return a negative error code, and didn't actually check for the error in the caller. And it didn't actually work at all. BenH bisected down odd tty behavior to it: "It looks like the patch is causing some major malfunctions of the X server for me, possibly related to PTYs. For example, cat'ing a large file in a gnome terminal hangs the kernel for -minutes- in a loop of what looks like flush_to_ldisc/workqueue code, (some ftrace data in the quoted bits further down). ... Some more data: It -looks- like what happens is that the flush_to_ldisc work queue entry constantly re-queues itself (because the PTY is full ?) and the workqueue thread will basically loop forver calling it without ever scheduling, thus starving the consumer process that could have emptied the PTY." which is pretty much exactly the problem we fixed in a5660b41af6a.

2011-06-03UBIFS: fix clean znode counter corruption in error casesArtem Bityutskiy1-4/+5
UBIFS maintains per-filesystem and global clean znode counters ('c->clean_zn_cnt' and 'ubifs_clean_zn_cnt'). It is important to maintain correct values there since the shrinker relies on 'ubifs_clean_zn_cnt'. However, in case of failures during commit the counters were corrupted. E.g., if a failure happens in the middle of 'write_index()', then some nodes in the commit list ('c->cnext') are marked as clean, and some are marked as dirty. And the 'ubifs_destroy_tnc_subtree()' frees does not retrun correct count, and we end up with non-zero 'c->clean_zn_cnt' when unmounting. This means that if we have 2 file-sytem and one of them fails, and we unmount it, 'ubifs_clean_zn_cnt' stays incorrect and confuses the shrinker.

UBIFS leaks memory on error path in 'ubifs_jnl_update()' in case of write failure because it forgets to free the 'struct ubifs_dent_node *dent' object.

Sometimes VM asks the shrinker to return amount of objects it can shrink, and we return the ubifs_clean_zn_cnt in that case. However, it is possible that this counter is negative for a short period of time, due to the way UBIFS TNC code updates it. And I can observe the following warnings sometimes: shrink_slab: ubifs_shrinker+0x0/0x2b7 [ubifs] negative objects to delete nr=-8541616642706119788 This patch makes sure UBIFS never returns negative count of objects.

2011-06-03ALSA: fm801: add error handling if auto-detect failsDan Carpenter1-2/+11
In the original code if auto detect failed and tea575x_tuner == 4 then we copy bogus information to chip->tea.card. I've changed the autodetect code to cleanup and return -ENODEV on error instead. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
