.. and also use it in lookup_one_len() rather than open-coding it. There aren't any performance-critical users, so inlining it is silly. But it wouldn't matter if it wasn't for the fact that the word-at-a-time dentry name patches want to conditionally replace the function, and uninlining it sets the stage for that. So again, this is a preparatory patch that doesn't change any semantics, and only prepares for a much cleaner and testable word-at-a-time dentry name accessor patch.

These don't change any semantics, but they clean up the code a bit and mark some arguments appropriately 'const'. They came up as I was doing the word-at-a-time dcache name accessor code, and cleaning this up now allows me to send out a smaller relevant interesting patch for the experimental stuff.

There is only one error code to return for a bad user-space buffer pointer passed to a system call in the same address space as the system call is executed, and that is EFAULT.

memblock allocator aligns @size to @align to reduce the amount of fragmentation. Commit: 7bd0b0f0 ("memblock: Reimplement memblock allocation using reverse free area iterator") Broke it by incorrectly relocating @size aligning to memblock_find_in_range_node(). As the aligned size is not propagated back to memblock_alloc_base_nid(), the actually reserved size isn't aligned. While this increases memory use for memblock reserved array, this shouldn't cause any critical failure; however, it seems that the size aligning was hiding a use-beyond-allocation bug in sparc64 and losing the aligning causes boot failure. The underlying problem is currently being debugged but this is a proper fix in itself, it's already pretty late in -rc cycle for boot failures and reverting the change for debugging isn't difficult. Restore the size aligning moving it to memblock_alloc_base_nid(). Reported-by: Meelis Roos <mroos@linux.ee> Signed-off-by: Tejun Heo <tj@kernel.org> Cc: David S.

Merge virtio pull request from Rusty Russell. * tag 'for-linus' of git://github.com/rustyrussell/linux: virtio: balloon: leak / fill balloon across S4
-
Amit Shah authored
commit e562966d added support for S4 to the balloon driver. The freeze function did nothing to free the pages, since reclaiming the pages from the host to immediately give them back (if S4 was successful) seemed wasteful. Also, if S4 wasn't successful, the guest would have to re-fill the balloon. On restore, the pages were supposed to be marked freed and the free page counters were incremented to reflect the balloon was totally deflated. However, this wasn't done right. The pages that were earlier taken away from the guest during a balloon inflation operation were just shown as used pages after a successful restore from S4. Just a fancy way of leaking lots of memory. Instead of trying that, just leak the balloon on freeze and fill it on restore/thaw paths. This works properly now. The optimisation to not leak can be added later on after a bit of refactoring of the code. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

The 'perf probe' command allows kprobe to be inserted at any offset from a function start, which results in adding kprobes to unintended location. (example: perf probe do_fork+10000 is allowed even though size of do_fork is ~904). My previous patch https://lkml.org/lkml/2012/2/24/42 addressed the case where DWARF info was available for the kernel. This patch fixes the case where perf probe is used on a kernel without debuginfo available.

IOMMU fixes for Linux 3.3-rc5 All the fixes are for the OMAP IOMMU driver. The first patch is the biggest one. It fixes the calls of the function omap_find_iovm_area() in the omap-iommu-debug module which expects a 'struct device' parameter since commit fabdbca8 instead of an omap_iommu handle. The omap-iommu-debug code still passed the handle to the function which caused a crash. The second patch fixes a NULL pointer dereference in the OMAP code and the third patch makes sure that the omap-iommu is initialized before the omap-isp driver, which relies on the iommu. The last patch is only a workaround until defered probing is implemented. * tag 'iommu-fixes-v3.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp iommu/omap: fix NULL pointer dereference iommu/omap: fix erroneous omap-iommu-debug API calls

This makes mount take slightly longer, but at the same time, the first write to the filesystem will be faster too. It also means that if there is a problem in the resource index, then we can refuse to mount rather than having to try and report that when the first write occurs. In addition, to avoid recursive locking, we hvae to take account of instances when the rindex glock may already be held when we are trying to update the rbtree of resource groups.

This patch fixes a problem whereby gfs2_grow was failing and causing GFS2 to assert. The problem was that when GFS2's fallocate operation tried to acquire an "allocation" it made sure the rindex was up to date, and if not, it called gfs2_rindex_update. However, if the file being fallocated was the rindex itself, it was already locked at that point. By calling gfs2_rindex_update at an earlier point in time, we bring rindex up to date and thereby avoid trying to lock it when the "allocation" is acquired.
