Patch from Catalin Marinas Chapter B2.7.3 in the latest ARM ARM (with v6 information) states that the completion of a TLB maintenance operation is only guaranteed by the execution of a DSB (Data Syncronization Barrier, formerly Data Write Barrier or Drain Write Buffer). Note that a DSB is only needed in the flush_tlb_kernel_* functions since the completion is guaranteed by a mode change (i.e. switching back to user mode) for the flush_tlb_user_* functions.

The point of the smaps "shared" is to count the number of pages that are mapped by more than one process, according to Mauricio Lin. However, smaps uses page_count for this, so it will return a false positive for every page that is mapped by just that one process, which is also in pagecache or swapcache. There are false positive situations for anonymous pages not in swapcache as well: - page reclaim, migration - get_user_pages (eg. direct-io, ptrace) Use page_mapcount instead, to count the number of mappings to the page. Use vm_normal_page so that weird things like /dev/mem aren't counted either. Signed-off-by:

ramfs neglects to update the directory mtime and ctime fields when creating a new symbolic link. Ramfs was modified in 2.6.15 to update these fields when other types of entries are created. The symlink support is separate from that other support, so that change did not cover quite all of the possibilities. All of the directory content manipulation entry points now seem to be covered with respect to these time field updates. Signed-off-by:

Change the format of numa_maps to be more compact and contain additional information that is useful for managing and troubleshooting memory on a NUMA system. Numa_maps can now also support huge pages. Fixes: 1. More compact format. Only display fields if they contain additional information. 2. Always display information for all vmas. The old numa_maps did not display vma with no mapped entries. This was a bit confusing because page migration removes ptes for file backed vmas. After page migration a part of the vmas vanished. 3. Rename maxref to maxmap. This is the maximum mapcount of all the pages in a vma and may be used as an indicator as to how many processes may be using a certain vma. 4. Include the ability to scan over huge page vmas. New items shown: dirty Number of pages in a vma that have either the dirty bit set in the page_struct or in the pte. file=<filename> The file backing the pages if any stack Stack area heap Heap area huge Huge page area. The number of pages shows is the number of huge pages not the regular sized pages. swapcache Number of pages with swap references. Must be >0 in order to be shown. active Number of active pages. Only displayed if different from the number of pages mapped. writeback Number of pages under writeback. Only displayed if >0.

Also from Thomas Gleixner <tglx@linutronix.de> Function next_timer_interrupt() got broken with a recent patch 6ba1b912 as sys_nanosleep() was moved to hrtimer. This broke things as next_timer_interrupt() did not check hrtimer tree for next event. Function next_timer_interrupt() is needed with dyntick (CONFIG_NO_IDLE_HZ, VST) implementations, as the system can be in idle when next hrtimer event was supposed to happen. At least ARM and S390 currently use next_timer_interrupt(). Signed-off-by:

Just to be safe, we should not trigger a conditional reschedule during the early boot sequence. We've historically done some questionable early on, and the safety warnings in __might_sleep() are generally turned off during that period, so there might be problems lurking. This affects CONFIG_PREEMPT_VOLUNTARY, which takes over might_sleep() to cause a voluntary conditional reschedule. Acked-by:

We want to use the "struct slab" size, not the size of the pointer to same. As it is, we'd not print out the last <n> entry pointers in the slab (where <n> is ~10, depending on whether it's a 32-bit or 64-bit kernel). Gaah, that slab code was written by somebody who likes unreadable crud. Signed-off-by: -

session when multiply mounted. Fixes slow response when cifs client is mounted to shares on multiple servers and oplock break occurs (usually due to attempt to multiply open a file). When treeids on mutiple mounted shares match and we find the wrong match first, we searched for the wrong cached files to send oplock break response for which usually meant that no matching file was found and thus the server would have to timeout the notification. Oplock break timeout is about 20 seconds on some servers so this could cause significantly slower performance on file open calls in a few cases (in particular when multiple shares are mounted from multiple servers, tree ids match, and we have a cached file which is later opened multiple times). This was the most important of the bugs that was found and fixed at Connectathon (interoperability testing event) this week.
