The gpio_twl4030_probe() function calls gpio_twl4030_remove(), and the former has __devinit, so the latter cannot use __devexit. Otherwise we hit the section mismatch warning: WARNING: drivers/gpio/built-in.o(.devinit.text+0x71a): Section mismatch in reference from the function _gpio_twl4030_probe() to the function .devexit.text:_gpio_twl4030_remove() The function __devinit _gpio_twl4030_probe() references a function __devexit _gpio_twl4030_remove(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of _gpio_twl4030_remove() so it may be used outside an exit section.

Isolators putting a page back to the LRU do not hold the page lock, and if the page is mlocked, another thread might munlock it concurrently. Expecting this, the putback code re-checks the evictability of a page when it just moved it to the unevictable list in order to correct its decision. The problem, however, is that ordering is not garuanteed between setting PG_lru when moving the page to the list and checking PG_mlocked afterwards: #0: #1 spin_lock() if (TestClearPageMlocked()) if (PageLRU()) move to evictable list SetPageLRU() spin_unlock() if (!PageMlocked()) move to evictable list The PageMlocked() check may get reordered before SetPageLRU() in #0, resulting in #0 not moving the still mlocked page, and in #1 failing to isolate and move the page as well. The page is now stranded on the unevictable list. The race condition is very unlikely. The consequence currently is one page falling off the reclaim grid and eventually getting freed with PG_unevictable set, which triggers a warning in the page allocator. TestClearPageMlocked() in #1 already provides full memory barrier semantics. This patch adds an explicit full barrier to force ordering between SetPageLRU() and PageMlocked() so that either one of the competitors rescues the page.

A particular fsfuzzer run caused an hfs file system to crash on mount. This is due to a corrupted MDB extent record causing a miscalculation of HFS_I(inode)->first_blocks for the extent tree. If the extent records are zereod out, it won't trigger the first_blocks special case. Instead it falls through to the extent code which we're still in the middle of initializing. This patch catches the 0 size extent records, reports the corruption, and fails the mount.

As found in <http://bugs.debian.org/550010>, hfsplus is using type u32 rather than sector_t for some sector number calculations. In particular, hfsplus_get_block() does: u32 ablock, dblock, mask; ... map_bh(bh_result, sb, (dblock << HFSPLUS_SB(sb).fs_shift) + HFSPLUS_SB(sb).blockoffset + (iblock & mask)); I am not confident that I can find and fix all cases where a sector number may be truncated. For now, avoid data loss by refusing to mount HFS+ volumes with more than 2^32 sectors (2TB).

After a discussion we agreed that we can move proc_sid_connector from __set_special_pids to sys_setsid. We also agreed that it is sufficient to change the check from task_session(curr) != pid into err > 0, since if we don't change the session, this means we were already the leader and return -EPERM. One last thing: There is also daemonize(), and some people might want to get a notification in that case. Since daemonize() is only needed if a user space does kernel_thread this does not look important (and there seems to be no consensus if this connector should be called in daemonize). If we really want this, we can add proc_sid_connector to daemonize() in an additional patch (Scott?)

Given such a long name, the kB count in /proc/meminfo's HardwareCorrupted line is being shown too far right (it does align with x86_64's VmallocChunk above, but I hope nobody will ever have that much corrupted!). Align it.

Memory failure on a KSM page currently oopses on its NULL anon_vma in page_lock_anon_vma(): that may not be much worse than the consequence of ignoring it, but it is better to be consistent with how ZERO_PAGE and hugetlb pages and other awkward cases are treated. Just skip it. We could fix it for 2.6.32 at the KSM end, by putting a dummy anon_vma pointer in there; but that would get harder next time, when KSM will put a pointer to something else there (and I'm not currently planning to do any work to open that up to memory_failure). So I would prefer this simple PageKsm test, until the other exceptions are handled.

When CONFIG_CPU_FREQ is disabled, cpufreq_get() needs a stub. Used by kvm (although it looks like a bit of the kvm code could be omitted when CONFIG_CPU_FREQ is disabled). arch/x86/built-in.o: In function `kvm_arch_init': (.text+0x10de7): undefined reference to `cpufreq_get' (Needed in linux-next's KVM tree, but it's correct in 2.6.32).

This reverts "Add serial number support for virtio_blk, V4a". Turns out that virtio_pci, lguest and s/390 all have an 8 bit limit on virtio config space, so noone could ever use this.
