       "Enable the SWIOTLB under 32-bit PAE kernels.
      
        Nowadays most distros enable this due to CONFIG_HYPERVISOR|XEN=y which
        select SWIOTLB.  But for those that are not interested in
        virtualization and wanting to use 32-bit PAE kernels and wanting to
        have working DMA operations - this configures it for them"

      namei: results of d_is_negative() should be checked after dentry revalidation · daf3761c

       "After switching to version 4.1.6, our parallelized and distributed
        workflows now fail consistently with errors of the form:
      
        T34: ./regex.c:39:22: error: config.h: No such file or directory
      
        From our 'git bisect' testing, the following commit appears to be the
        possible cause of the behavior we've been seeing: commit 766c4cbf"
      
      Al Viro says:
       "What happens is that 766c4cbf got the things subtly wrong.
      
        We used to treat d_is_negative() after lookup_fast() as "fall with
        ENOENT".  That was wrong - checking ->d_flags outside of ->d_seq
        protection is unreliable and failing with hard error on what should've
        fallen back to non-RCU pathname resolution is a bug.
      
        Unfortunately, we'd pulled the test too far up and ran afoul of
        another kind of staleness.  The dentry might have been absolutely
        stable from the RCU point of view (and we might be on UP, etc), but
        stale from the remote fs point of view.  If ->d_revalidate() returns
        "it's actually stale", dentry gets thrown away and the original code
        wouldn't even have looked at its ->d_flags.
      
        What we need is to check ->d_flags where 766c4cbf does (prior to
        ->d_seq validation) but only use the result in cases where we do not
        discard this dentry outright"

         - Two devfreq fixes, one for a double kfree() in an error code path
           and one for a confusing sysfs-related failure (Geliang Tang, Tobias

      dm snapshot: add new persistent store option to support overflow · b0d3cc01
      Mike Snitzer authored
      Commit 76c44f6d introduced the possibly for "Overflow" to be reported
      by the snapshot device's status.  Older userspace (e.g. lvm2) does not
      handle the "Overflow" status response.
      
      Fix this incompatibility by requiring newer userspace code, that can
      cope with "Overflow", request the persistent store with overflow support
      by using "PO" (Persistent with Overflow) for the snapshot store type.

      dm cache: fix NULL pointer when switching from cleaner policy · 2bffa150
      Joe Thornber authored
      The cleaner policy doesn't make use of the per cache block hint space in
      the metadata (unlike the other policies).  When switching from the
      cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block)
      was observed.  The crash was caused by bugs in dm-cache-metadata.c
      when trying to skip creation of the hint btree.
      
      The minimal fix is to change hint size for the cleaner policy to 4 bytes
      (only hint size supported).
