2010-12-14ext4: Turn off multiple page-io submission by defaultTheodore Ts'o3-3/+17
Jon Nelson has found a test case which causes postgresql to fail with the error: psql:t.sql:4: ERROR: invalid page header in block 38269 of relation base/16384/16581 Under memory pressure, it looks like part of a file can end up getting replaced by zero's. Until we can figure out the cause, we'll roll back the change and use block_write_full_page() instead of ext4_bio_write_page(). The new, more efficient writing function can be used via the mount option mblk_io_submit, so we can test and fix the new page I/O code. To reproduce the problem, install postgres 8.4 or 9.0, and pin enough memory such that the system just at the end of triggering writeback before running the following sql script: begin; create temporary table foo as select x as a, ARRAY[x] as b FROM generate_series(1, 10000000 ) AS x; create index foo_a_idx on foo (a); create index foo_b_idx on foo USING GIN (b); rollback; If the temporary table is created on a hard drive partition which is encrypted using dm_crypt, then under memory pressure, approximately 30-40% of the time, pgsql will issue the above failure. This patch should fix this problem, and the problem will come back if the file system is mounted with the mblk_io_submit mount option.

2010-12-14workqueue: It is likely that WORKER_NOT_RUNNING is trueSteven Rostedt1-2/+2
Running the annotate branch profiler on three boxes, including my main box that runs firefox, evolution, xchat, and is part of the distcc farm, showed this with the likelys in the workqueue code: correct incorrect % Function File Line ------- --------- - -------- ---- ---- 96 996253 99 wq_worker_sleeping workqueue.c 703 96 996247 99 wq_worker_waking_up workqueue.c 677 The likely()s in this case were assuming that WORKER_NOT_RUNNING will most likely be false. But this is not the case. The reason is (and shown by adding trace_printks and testing it) that most of the time WORKER_PREP is set. In worker_thread() we have: worker_clr_flags(worker, WORKER_PREP); [ do work stuff ] worker_set_flags(worker, WORKER_PREP, false); (that 'false' means not to wake up an idle worker) The wq_worker_sleeping() is called from schedule when a worker thread is putting itself to sleep. Which happens most of the time outside of that [ do work stuff ]. The wq_worker_waking_up is called by the wakeup worker code, which is also callod outside that [ do work stuff ]. Thus, the likely and unlikely used by those two functions are actually backwards. Remove the annotation and let gcc figure it out.

2010-12-13kgdboc,input: Fix regression with keyboard release key and early debuggingJason Wessel1-1/+2
The commit 111c182340cd22e238ab1cc6564df336c6ebd7cb (kgdboc: reset input devices (keyboards) when exiting debugger) introduced a regression in early debugging such that you get a kernel oops on continue (with the go command) if you boot a kernel with: earlyprintk=vga ekgdboc=kbd kgdbwait The restore kgdboc_restore_input() routine schedules work for the purpose of sending key release events for any keys that were in the depressed state prior to entering the kernel debugger. A simple fix to the crash is to not invoke the schedule_work() if the kernel system_state is anything other than SYSTEM_RUNNING.

2010-12-13Btrfs: prevent RAID level downgrades when space is lowChris Mason1-1/+19
The extent allocator has code that allows us to fill allocations from any available block group, even if it doesn't match the raid level we've requested. This was put in because adding a new drive to a filesystem made with the default mkfs options actually upgrades the metadata from single spindle dup to full RAID1. But, the code also allows us to allocate from a raid0 chunk when we really want a raid1 or raid10 chunk. This can cause big trouble because mkfs creates a small (4MB) raid0 chunk for data and metadata which then goes unused for raid1/raid10 installs. The allocator will happily wander in and allocate from that chunk when things get tight, which is not correct. The fix here is to make sure that we provide duplication when the caller has asked for it. It does all the dups to be any raid level, which preserves the dup->raid1 upgrade abilities.

2010-12-13Btrfs: account for missing devices in RAID allocation profilesChris Mason3-3/+36
When we mount in RAID degraded mode without adding a new device to replace the failed one, we can end up using the wrong RAID flags for allocations. This results in strange combinations of block groups (raid1 in a raid10 filesystem) and corruptions when we try to allocate blocks from single spindle chunks on drives that are actually missing. The first device has two small 4MB chunks in it that mkfs creates and these are usually unused in a raid1 or raid10 setup. But, in -o degraded, the allocator will fall back to these because the mask of desired raid groups isn't correct. The fix here is to count the missing devices as we build up the list of devices in the system. This count is used when picking the raid level to make sure we continue using the same levels that were in place before we lost a drive. Signed-off-by: Chris Mason <[email protected]>

2010-12-13Btrfs: EIO when we fail to read tree rootsChris Mason1-1/+4
If we just get a plain IO error when we read tree roots, the code wasn't properly sending that error up the chain. This allowed mounts to continue when they should failed, and allowed operations on partially setup root structs. The end result was usually oopsen on spinlocks that hadn't been spun up correctly.

2010-12-13hwmon: (ltc4215) make sysfs file match the alarm causeIra W. Snyder1-2/+2
The ltc4215 driver used the chip's "power good" status bit to provide the power1_alarm file. This is wrong: the chip is really reporting the status of one of the monitored voltages. Change the sysfs file from power1_alarm to in2_min_alarm instead. This matches the voltage that the chip is raising an alarm for. Signed-off-by: Ira W.

2010-12-12ARM: 6528/1: Use CTR for the I-cache line size on ARMv7Catalin Marinas2-10/+27
The current implementation of the v7_coherent_*_range function assumes that the D and I cache lines have the same size, which is incorrect architecturally. This patch adds the icache_line_size macro which reads the CTR register. The main loop in v7_coherent_*_range is split in two independent loops or the D and I caches. This also has the performance advantage that the DSB is moved outside the main loop.
