2014-01-29mm: numa: initialise numa balancing after jump label initialisationMel Gorman1-6/+11
The command line parsing takes place before jump labels are initialised which generates a warning if numa_balancing= is specified and CONFIG_JUMP_LABEL is set. On older kernels before commit c4b2c0c5f647 ("static_key: WARN on usage before jump_label_init was called") the kernel would have crashed. This patch enables automatic numa balancing later in the initialisation process if numa_balancing= is specified.

2014-01-29mm/page-writeback.c: do not count anon pages as dirtyable memoryJohannes Weiner4-27/+5
The VM is currently heavily tuned to avoid swapping. Whether that is good or bad is a separate discussion, but as long as the VM won't swap to make room for dirty cache, we can not consider anonymous pages when calculating the amount of dirtyable memory, the baseline to which dirty_background_ratio and dirty_ratio are applied. A simple workload that occupies a significant size (40+%, depending on memory layout, storage speeds etc.) of memory with anon/tmpfs pages and uses the remainder for a streaming writer demonstrates this problem. In that case, the actual cache pages are a small fraction of what is considered dirtyable overall, which results in an relatively large portion of the cache pages to be dirtied. As kswapd starts rotating these, random tasks enter direct reclaim and stall on IO. Only consider free pages and file pages dirtyable.

2014-01-29mm/page-writeback.c: fix dirty_balance_reserve subtraction from dirtyable memoryJohannes Weiner1-31/+24
Tejun reported stuttering and latency spikes on a system where random tasks would enter direct reclaim and get stuck on dirty pages. Around 50% of memory was occupied by tmpfs backed by an SSD, and another disk (rotating) was reading and writing at max speed to shrink a partition. : The problem was pretty ridiculous. It's a 8gig machine w/ one ssd and 10k : rpm harddrive and I could reliably reproduce constant stuttering every : several seconds for as long as buffered IO was going on on the hard drive : either with tmpfs occupying somewhere above 4gig or a test program which : allocates about the same amount of anon memory. Although swap usage was : zero, turning off swap also made the problem go away too. : : The trigger conditions seem quite plausible - high anon memory usage w/ : heavy buffered IO and swap configured - and it's highly likely that this : is happening in the wild too. (this can happen with copying large files : to usb sticks too, right?) This patch (of 2): The dirty_balance_reserve is an approximation of the fraction of free pages that the page allocator does not make available for page cache allocations. As a result, it has to be taken into account when calculating the amount of "dirtyable memory", the baseline to which dirty_background_ratio and dirty_ratio are applied. However, currently the reserve is subtracted from the sum of free and reclaimable pages, which is non-sensical and leads to erroneous results when the system is dominated by unreclaimable pages and the dirty_balance_reserve is bigger than free+reclaimable. In that case, at least the already allocated cache should be considered dirtyable. Fix the calculation by subtracting the reserve from the amount of free pages, then adding the reclaimable pages on top.

2014-01-29mm: document improved handling of swappiness==0Aaron Tomlin1-1/+3
Prior to commit fe35004fbf9e ("mm: avoid swapping out with swappiness==0") setting swappiness to 0, reclaim code could still evict recently used user anonymous memory to swap even though there is a significant amount of RAM used for page cache. The behaviour of setting swappiness to 0 has since changed. When set, the reclaim code does not initiate swap until the amount of free pages and file-backed pages, is less than the high water mark in a zone. Let's update the documentation to reflect this.

2014-01-29ceph: fix posix ACL hooksSage Weil4-5/+10
The merge of commit 7221fe4c2ed7 ("ceph: add acl for cephfs") raced with upstream changes in the generic POSIX ACL code (eg commit 2aeccbe957d0 "fs: add generic xattr_acl handlers" and others). Some of the fallout was fixed in commit 4db658ea0ca ("ceph: Fix up after semantic merge conflict"), but it was incomplete: the set_acl inode_operation wasn't getting set, and the prototype needed to be adjusted a bit (it doesn't take a dentry anymore).

2014-01-28sparc: don't use module_init in non-modular pci.c codePaul Gortmaker1-2/+1
The pci.o is built for SPARC64_PCI -- which is bool, and hence this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall can be somewhat misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering.

2014-01-28sparc: delete non-required instances of include <linux/init.h>Paul Gortmaker18-18/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2014-01-28drivers: ide: Include appropriate header file in ide-pio-blacklist.cRashika Kheria1-0/+1
Include appropriate header file include/linux/ide.h in file ide-pio-blacklist.c because function ide_scan_pio_blacklist() has it's prototype declaration in include/linux/ide.h.

Also, include linux/ide.h because it contains certain declarations necessary for including ide-cd.h.

blackfin: bf60x: clock: return 0 upon error from clk_round_rate() clk_round_rate() should return 0 upon an error, rather than returning a negative error code. This is because clk_round_rate() is being changed to return an unsigned return type rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz.

2014-01-2906/18] smp, blackfin: kill SMP single function call interruptJiang Liu1-5/+1
Commit 9a46ad6d6df3b54 "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" has unified the way to handle single and multiple cross-CPU function calls. Now only one interrupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.
