2011-01-19hrtimers: Notify hrtimer users of switches to NOHZ modeStephen Boyd
When NOHZ=y and high res timers are disabled (via cmdline or Kconfig) tick_nohz_switch_to_nohz() will notify the user about switching into NOHZ mode. Nothing is printed for the case where HIGH_RES_TIMERS=y. Fix this for the HIGH_RES_TIMERS=y case by duplicating the printk from the low res NOHZ path in the high res NOHZ path. This confused me since I was thinking 'dmesg | grep -i NOHZ' would tell me if NOHZ was enabled, but if I have hrtimers there is nothing.

2011-01-19perf: Fix find_get_context() vs perf_event_exit_task() raceOleg Nesterov
find_get_context() must not install the new perf_event_context if the task has already passed perf_event_exit_task(). If nothing else, this means the memory leak. Initially ctx->refcount == 2, it is supposed that perf_event_exit_task_context() should participate and do the necessary put_ctx(). find_lively_task_by_vpid() checks PF_EXITING but this buys nothing, by the time we call find_get_context() this task can be already dead. To the point, cmpxchg() can succeed when the task has already done the last schedule(). Change find_get_context() to populate task->perf_event_ctxp[] under task->perf_event_mutex, this way we can trust PF_EXITING because perf_event_exit_task() takes the same mutex. Also, change perf_event_exit_task_context() to use rcu_dereference(). Probably this is not strictly needed, but with or without this change find_get_context() can race with setup_new_exec()->perf_event_exit_task(), rcu_dereference() looks better.

2011-01-19cifs: don't fail writepages on -EAGAIN errorsJeff Layton
If CIFSSMBWrite2 returns -EAGAIN, then the error should be considered temporary. CIFS should retry the write instead of setting an error on the mapping and returning. For WB_SYNC_ALL, just retry the write immediately. In the WB_SYNC_NONE case, call redirty_page_for_writeback on all of the pages that didn't get written out and then move on. Also, fix up the handling of a short write with a successful return code. MS-CIFS says that 0 bytes_written means ENOSPC or EFBIG. It doesn't mention what a short, but non-zero write means, so for now treat it as we would an -EAGAIN return.

2011-01-19ceph: avoid immediate cap check after importSage Weil

2011-01-19ceph: fix flushing of caps vs cap importSage Weil
If we are mid-flush and a cap is migrated to another node, we need to resend the cap flush message to the new MDS, and do so with the original flush_seq to avoid leaking across a sync boundary. Previously we didn't redo the flush (we only flushed newly dirty data), which would cause a later sync to hang forever. Signed-off-by: Sage Weil <sage@newdream.net>

2011-01-19Bluetooth: Fix race condition with conn->sec_levelJohan Hedberg
The conn->sec_level value is supposed to represent the current level of security that the connection has. However, by assigning to it before requesting authentication it will have the wrong value during the authentication procedure. To fix this a pending_sec_level variable is added which is used to track the desired security level while making sure that sec_level always represents the current level of security.

2011-01-19Bluetooth: Fix authentication request for L2CAP raw socketsJohan Hedberg
When there is an existing connection l2cap_check_security needs to be called to ensure that the security level of the new socket is fulfilled.

2011-01-19Revert "Bluetooth: Update sec_level/auth_type for already existing connections"Johan Hedberg
This reverts commit 045309820afe047920a50de25634dab46a1e851d. That commit is wrong for two reasons: - The conn->sec_level shouldn't be updated without performing authentication first (as it's supposed to represent the level of security that the existing connection has) - A higher auth_type value doesn't mean "more secure" like the commit seems to assume. E.g. dedicated bonding with MITM protection is 0x03 whereas general bonding without MITM protection is 0x04. hci_conn_auth already takes care of updating conn->auth_type so hci_connect doesn't need to do it.

o Jeff Moyer was doing some testing on a RAM backed disk and blkiocg_lookup_group() showed up high overhead after memcpy(). Similarly somebody else reported that blkiocg_lookup_group() is eating 6% extra cpu. Though looking at the code I can't think why the overhead of this function is so high. One thing is that it is called with very high frequency (once for every IO). o For lot of folks blkio controller will be compiled in but they might not have actually created cgroups. Hence optimize the case of root cgroup where we can avoid calling blkiocg_lookup_group() if IO is happening in root group (common case).

But if I do like this: blktrace /dev/sdb -a issue -a complete -o - | blkparse -i - I only want to see 'D' and 'C', while with the following command dd if=/mnt/ocfs2/test of=/dev/null bs=4k count=1 iflag=direct I will get(with a 2.6.37 vanilla kernel): 8,16 0 0 0.000000000 0 m N cfq3805 alloced 8,16 0 0 0.000004126 0 m N cfq3805 insert_request 8,16 0 0 0.000004884 0 m N cfq3805 add_to_rr 8,16 0 0 0.000008417 0 m N cfq workload slice:300 8,16 0 0 0.000009557 0 m N cfq3805 set_active wl_prio:0 wl_type:2 8,16 0 0 0.000010640 0 m N cfq3805 fifo= (null) 8,16 0 0 0.000011193 0 m N cfq3805 dispatch_insert 8,16 0 0 0.000012221 0 m N cfq3805 dispatched a request 8,16 0 0 0.000012802 0 m N cfq3805 activate rq, drv=1 8,16 0 1 0.000013181 3805 D R 114759 + 8 [dd] 8,16 0 2 0.000164244 0 C R 114759 + 8 [0] 8,16 0 0 0.000167997 0 m N cfq3805 complete rqnoidle 0 8,16 0 0 0.000168782 0 m N cfq3805 set_slice=100 8,16 0 0 0.000169874 0 m N cfq3805 arm_idle: 8 group_idle: 0 8,16 0 0 0.000170189 0 m N cfq schedule dispatch 8,16 0 0 0.000397938 0 m N cfq3805 slice expired t=0 8,16 0 0 0.000399763 0 m N cfq3805 sl_used=1 disp=1 charge=1 iops=0 sect=8 8,16 0 0 0.000400227 0 m N cfq3805 del_from_rr 8,16 0 0 0.000400882 0 m N cfq3805 put_queue See, there are 19 lines while I only need 2. I don't think it is appropriate for a user. So this patch will disable any messages if the BLK_TC_NOTIFY isn't set. Now the output for the same command will look like: 8,16 0 1 0.000000000 4908 D R 114759 + 8 [dd] 8,16 0 2 0.000146827 0 C R 114759 + 8 [0] Yes, it is what I want to see.

2011-01-19[media] staging/lirc: fix mem leaks and ptr err usageJarod Wilson
When the lirc drivers were converted over to using memdup_user, I mistakenly also removed corresponding calls to kfree. Add those back. I also screwed up on the allocation error check in lirc_serial, using if (PTR_ERR()) instead of if (IS_ERR()), which broke transmit.

2011-01-19[media] hdpvr: reduce latency of i2c read/write w/recycled bufferJarod Wilson
The current hdpvr code kmalloc's a new buffer for every i2c read and write. Rather than do that, lets allocate a buffer in the driver's device struct and just use that every time. The size I've chosen for the buffer is the maximum size I could ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up to 128). Note that this might also remedy user reports of very sluggish behavior of IR receive with hdpvr hardware. v2: make sure (len <= (dev->i2c_buf)) [Jean Delvare] Reported-by: Jean Delvare <khali@linux-fr.org> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-01-19[media] hdpvr: enable IR partJarod Wilson
A number of things going on here, but the end result is that the IR part on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or lirc_zilog. First up, there are some conditional build fixes that come into play whether i2c is built-in or modular. Second, we're swapping out i2c_new_probed_device() for i2c_new_device(), as in my testing, probing always fails, but we *know* that all hdpvr devices have a z8 chip at 0x70 and 0x71. Third, we're poking at an i2c address directly without a client, and writing some magic bits to actually turn on this IR part (this could use some improvement in the future). Fourth, some of the i2c_adapter storage has been reworked, as the existing implementation used to lead to an oops following i2c changes c. 2.6.31. Earlier editions of this patch have been floating around the 'net for a while, including being patched into Fedora kernels, and they *do* work. This specific version isn't yet tested, beyond loading ir-kbd-i2c and confirming that it does bind to the RX address of the hdpvr. [mchehab@redhat.com: I2C_CLASS_TV_ANALOG is not defined.

2011-01-19[media] rc/mceusb: timeout should be in ns, not usJarod Wilson
Fixes an egregious bug in mceusb driver, where the receiver was being put into idle mode far sooner than it should have, thanks to storing a timeout value that in us where it should be ns. Basically, the receiver kept going into idle mode before a trailing space had been fully received, which was causing problems for some protocols, most notably manifesting as lirc userspace never receiving a trailing space for any rc5 signals.
