Commit d01730d7 didn't completely fix the problem since we still take dqio_mutex and i_mutex in the wrong order. Move taking of i_mutex further down (luckily it's needed only for updating inode flags) below where dqio_mutex is taken.

Once a structure goes over PAGE_SIZE*2, we see occasional allocation failures. Some people have chosen to switch over to things like vmalloc() that will let them keep array-like access to such a large structures. But, vmalloc() has plenty of downsides. Here's an alternative. I think it's what Andrew was suggesting here: http://lkml.org/lkml/2009/7/2/518 I call it a flexible array. It does all of its work in PAGE_SIZE bits, so never does an order>0 allocation. The base level has PAGE_SIZE-2*sizeof(int) bytes of storage for pointers to the second level. So, with a 32-bit arch, you get about 4MB (4183112 bytes) of total storage when the objects pack nicely into a page. It is half that on 64-bit because the pointers are twice the size. There's a table detailing this in the code. There are kerneldocs for the functions, but here's an overview: flex_array_alloc() - dynamically allocate a base structure flex_array_free() - free the array and all of the second-level pages flex_array_free_parts() - free the second-level pages, but not the base (for static bases) flex_array_put() - copy into the array at the given index flex_array_get() - copy out of the array at the given index flex_array_prealloc() - preallocate the second-level pages between the given indexes to guarantee no allocs will occur at put() time. We could also potentially just pass the "element_size" into each of the API functions instead of storing it internally. That would get us one more base pointer on 32-bit. I've been testing this by running it in userspace. The header and patch that I've been using are here, as well as the little script I'm using to generate the size table which goes in the kerneldocs. http://sr71.net/~dave/linux/flexarray/ [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: NDave Hansen <dave@linux.vnet.ibm.com> Reviewed-by: NKAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Since commit 8dfd0374 ("MMC core: limit minimum initialization frequency to 400kHz") MMC core checks for minimum frequency, and that causes following messages flood when using eSDHC controllers: ... mmc0: Minimum clock frequency too high for identification mode mmc0: Minimum clock frequency too high for identification mode ... The warnings are legitimate, since if we'd use 133 MHz clocks for standard SDHCI controllers, we'd not able to scale frequency down to 400 kHz. But eSDHC controllers have a non-standard SD clock management, so we can divide clock by 256 * 16, not just 256. This patch introduces get_min_clock() callback for sdhci core and implements it for sdhci-of driver, and thus fixes the issue.

由 Hidetoshi Seto 提交于
commit d6580a9f ("kexec: sysrq: simplify sysrq-c handler") changed the behavior of sysrq-c to unconditional dereference of NULL pointer. So in cases with CONFIG_KEXEC, where crash_kexec() was directly called from sysrq-c before, now it can be said that a step of "real oops" was inserted before starting kdump. However, in contrast to oops via SysRq-c from keyboard which results in panic due to in_interrupt(), oops via "echo c > /proc/sysrq-trigger" will not become panic unless panic_on_oops=1. It means that even if dump is properly configured to be taken on panic, the sysrq-c from proc interface might not start crashdump while the sysrq-c from keyboard can start crashdump. This confuses traditional users of kdump, i.e. people who expect sysrq-c to do common behavior in both of the keyboard and proc interface. This patch brings the keyboard and proc interface behavior of sysrq-c in line, by forcing panic_on_oops=1 before oops in sysrq-c handler. And some updates in documentation are included, to clarify that there is no longer dependency with CONFIG_KEXEC, and that now the system can just crash by sysrq-c if no dump mechanism is configured.

The page allocator warns once when an order >= MAX_ORDER is specified. This is to catch callers of the allocator that are always falling back to their worst-case when it was not expected. However, there are cases where the caller is behaving correctly but cannot suppress the warning. This patch allows the warning to be suppressed by the callers by specifying __GFP_NOWARN.

After commit ec64f515 ("cgroup: fix frequent -EBUSY at rmdir"), cgroup's rmdir (especially against memcg) doesn't return -EBUSY by temporary ref counts. That commit expects all refs after pre_destroy() is temporary but...it wasn't. Then, rmdir can wait permanently. This patch tries to fix that and change followings. - set CGRP_WAIT_ON_RMDIR flag before pre_destroy(). - clear CGRP_WAIT_ON_RMDIR flag when the subsys finds racy case. if there are sleeping ones, wakes them up. - rmdir() sleeps only when CGRP_WAIT_ON_RMDIR flag is set.

Under certain circumstances msleep(1) within the loop, which waits for the EEPROM to be finished, might take longer than the timeout. On the next loop the status register might now return to be ready and therefore the loop finishes. The following check now tests if a timeout occurred and if so returns an error although the device reported it was ready. This fix replaces testing the occurrence of the timeout by testing the "not ready" bit in the status register.

The bug was introduced by commit cc31edce ("cgroups: convert tasks file to use a seq_file with shared pid array"). We cache a pid array for all threads that are opening the same "tasks" file, but the pids in the array are always from the namespace of the last process that opened the file, so all other threads will read pids from that namespace instead of their own namespaces. To fix it, we maintain a list of pid arrays, which is keyed by pid_ns. The list will be of length 1 at most time.

This is because hugetlb_unreserve_pages() is unconditionally removing blocks_per_huge_page(h) on each call rather than using the freed amount. If there were 0 blocks, it goes negative, resulting in the above. This is a regression from commit a5516438 ("hugetlb: modular state for hugetlb page size") which did: - inode->i_blocks -= BLOCKS_PER_HUGEPAGE * freed; + inode->i_blocks -= blocks_per_huge_page(h); so just put back the freed multiplier, and it's all happy again.

rtc-cmos has two drivers, one PNP and one platform. When PNP has not succeeded probing, platform is registered. However, it tries to unregister both drivers unconditionally, instead of only unregistering those that were successfully registered.
