space read" This reverts commit 47970b1b2aa64464bc0a9543e86361a622ae7c03. It turns out it breaks several distributions. Looks like the stricter selinux checks fail due to selinux policies not being set to allow the access - breaking X, but also lspci. So while the change was clearly the RightThing(tm) to do in theory, in practice we have backwards compatibility issues making it not work.

2011-02-12jbd2: call __jbd2_log_start_commit with j_state_lock write lockedTheodore Ts'o2-9/+21
On an SMP ARM system running ext4, I've received a report that the first J_ASSERT in jbd2_journal_commit_transaction has been triggering: J_ASSERT(journal->j_running_transaction != NULL); While investigating possible causes for this problem, I noticed that __jbd2_log_start_commit() is getting called with j_state_lock only read-locked, in spite of the fact that it's possible for it might j_commit_request. Fix this by grabbing the necessary information so we can test to see if we need to start a new transaction before dropping the read lock, and then calling jbd2_log_start_commit() which will grab the write lock.

2011-02-12ext4: serialize unaligned asynchronous DIOEric Sandeen5-18/+100
ext4 has a data corruption case when doing non-block-aligned asynchronous direct IO into a sparse file, as demonstrated by xfstest 240. The root cause is that while ext4 preallocates space in the hole, mappings of that space still look "new" and dio_zero_block() will zero out the unwritten portions. When more than one AIO thread is going, they both find this "new" block and race to zero out their portion; this is uncoordinated and causes data corruption. Dave Chinner fixed this for xfs by simply serializing all unaligned asynchronous direct IO. I've done the same here. The difference is that we only wait on conversions, not all IO. This is a very big hammer, and I'm not very pleased with stuffing this into ext4_file_write(). But since ext4 is DIO_LOCKING, we need to serialize it at this high level. I tried to move this into ext4_ext_direct_IO, but by then we have the i_mutex already, and we will wait on the work queue to do conversions - which must also take the i_mutex. So that won't work. This was originally exposed by qemu-kvm installing to a raw disk image with a normal sector-63 alignment. I've tested a backport of this patch with qemu, and it does avoid the corruption. It is also quite a lot slower (14 min for package installs, vs. 8 min for well-aligned) but I'll take slow correctness over fast corruption any day. Mingming suggested that we can track outstanding conversions, and wait on those so that non-sparse files won't be affected, and I've implemented that here; unaligned AIO to nonsparse files won't take a perf hit.

2011-02-12ext4: make grpinfo slab cache names staticEric Sandeen1-40/+60
In 2.6.37 I was running into oopses with repeated module loads & unloads. I tracked this down to: fb1813f4 ext4: use dedicated slab caches for group_info structures (this was in addition to the features advert unload problem) The kstrdup & subsequent kfree of the cache name was causing a double free. In slub, at least, if I read it right it allocates & frees the name itself, slab seems to do something different... so in slub I think we were leaking -our- cachep->name, and double freeing the one allocated by slub. After getting lost in slab/slub/slob a bit, I just looked at other sized-caches that get allocated. jbd2, biovec, sgpool all do it more or less the way jbd2 does. Below patch follows the jbd2 method of dynamically allocating a cache at mount time from a list of static names. (This might also possibly fix a race creating the caches with parallel mounts running).

2011-02-11drivers/w1/masters/omap_hdq.c: add missing clk_putJulia Lawall1-14/+14
This code makes two calls to clk_get, then test both return values and fails if either failed. The problem is that in the first inner if, where the first call to clk_get has failed, it don't know if the second call has failed as well. So it don't know whether clk_get should be called on the result of the second call. Of course, it would be possible to test that value again. A simpler solution is just to test the result of calling clk_get directly after each call. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ position p1,p2; expression e; statement S; @@ e = clk_get@p1(...) ... if@p2 (IS_ERR(e)) S @@ expression e; statement S; identifier l; position r.p1, p2 != r.p2; @@ *e = clk_get@p1(...) ... when != clk_put(e) *if@p2 (...) { ... when != clk_put(e) * return ...; }// </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Acked-by: Tony Lindgren <tony@atomide.com> Acked-by: Amit Kucheria <amit.kucheria@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-02-11vmscan: fix zone shrinking exit when scan work is doneJohannes Weiner1-2/+2
Commit 3e7d34497067 ("mm: vmscan: reclaim order-0 and use compaction instead of lumpy reclaim") introduced an indefinite loop in shrink_zone(). It meant to break out of this loop when no pages had been reclaimed and not a single page was even scanned. The way it would detect the latter is by taking a snapshot of sc->nr_scanned at the beginning of the function and comparing it against the new sc->nr_scanned after the scan loop. But it would re-iterate without updating that snapshot, looping forever if sc->nr_scanned changed at least once since shrink_zone() was invoked. This is not the sole condition that would exit that loop, but it requires other processes to change the zone state, as the reclaimer that is stuck obviously can not anymore. This is only happening for higher-order allocations, where reclaim is run back to back with compaction.

2011-02-11mlock: do not munlock pages in __do_fault()Michel Lespinasse1-6/+0
If the page is going to be written to, __do_page needs to break COW. However, the old page (before breaking COW) was never mapped mapped into the current pte (__do_fault is only called when the pte is not present), so vmscan can't have marked the old page as PageMlocked due to being mapped in __do_fault's VMA. Therefore, __do_fault() does not need to worry about clearing PageMlocked() on the old page.
