      There are few important bug fixes for LogFS
      
      * tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream:
        Logfs: Allow NULL block_isbad() methods
        logfs: Grow inode in delete path
        logfs: Free areas before calling generic_shutdown_super()
        logfs: remove useless BUG_ON
        MAINTAINERS: Add Prasad Joshi in LogFS maintiners
        logfs: Propagate page parameter to __logfs_write_inode
        logfs: set superblock shutdown flag after generic sb shutdown
        logfs: take write mutex lock during fsync and sync
        logfs: Prevent memory corruption
        logfs: update page reference count for pined pages
      
      Fix up conflict in fs/logfs/dev_mtd.c due to semantic change in what
      "mtd->block_isbad" means in commit f2933e86: "Logfs: Allow NULL
      block_isbad() methods" clashing with the abstraction changes in the
      commits 7086c19d: "mtd: introduce mtd_block_isbad interface" and
      d58b27ed: "logfs: do not use 'mtd->block_isbad' directly".
      
      This resolution takes the semantics from commit f2933e86, and just
      makes mtd_block_isbad() return zero (false) if the 'block_isbad'
      function is NULL.  But that also means that now "mtd_can_have_bb()"
      always returns 0.
      
      Now, "mtd_block_markbad()" will obviously return an error if the
      low-level driver doesn't support bad blocks, so this is somewhat
      non-symmetric, but it actually makes sense if a NULL "block_isbad"
      function is considered to mean "I assume that all my blocks are always
      good".

      perf top: Fix number of samples displayed · 509605db
      Stephane Eranian authored
      In recent versions of perf top, pressing the 'e' key to change the
      number of displayed samples had no effect.
      
      The number of samples was still dictated by the size of the terminal
      (stdio mode). That was quite annoying because typically only the first
      dozen samples really matter.
      
      This patch fixes this.

      perf tools: Fix strlen() bug in perf_event__synthesize_event_type() · d8d9c282
      Stephane Eranian authored
      The event_type record has a max length for the event name.
      
      It's called MAX_EVENT_NAME.
      
      The name may be truncated to fit the max length. But the header.size still
      reflects the original name length. If that length is > MAX_EVENT_NAME, then the
      header.size field is bogus. Fix this by using the length of the name after the
      potential truncation.

      perf tools: Fix broken build by defining _GNU_SOURCE in Makefile · 0a84f007
      David Daney authored
      When building on my Debian/mips system, util/util.c fails to build
      because commit 1aed2671 (perf kvm: Do
      guest-only counting by default) indirectly includes stdio.h before the
      feature selection in util.h is done.  This prevents _GNU_SOURCE in
      util.h from enabling the declaration of getline(), from now second
      inclusion of stdio.h, and the build is broken.
      
      There is another breakage in util/evsel.c caused by include ordering,
      but I didn't fully track down the commit that caused it.
      
      The root cause of all this is an inconsistent definition of _GNU_SOURCE,
      so I move the definition into the Makefile so that it is passed to all
      invocations of the compiler and used uniformly for all system header
      files.  All other #define and #undef of _GNU_SOURCE are removed as they
      cause conflicts with the definition passed to the compiler.
      
      All the features.h definitions (_LARGEFILE64_SOURCE _FILE_OFFSET_BITS=64
      and _GNU_SOURCE) are needed by the python glue code too, so they are
      moved to BASIC_CFLAGS, and the misleading comments about BASIC_CFLAGS
      are removed.
      
      This gives me a clean build on x86_64 (fc12) and mips (Debian).

      IB/mlx4: pass SMP vendor-specific attribute MADs to firmware · a6f7feae
      Jack Morgenstein authored
      In the current code, vendor-specific MADs (e.g with the FDR-10
      attribute) are silently dropped by the driver, resulting in timeouts
      at the sending side and inability to query/configure the relevant
      feature.  However, the ConnectX firmware is able to handle such MADs.
      For unsupported attributes, the firmware returns a GET_RESPONSE MAD
      containing an error status.
      
      For example, for a FDR-10 node with LID 11:
      
          # ibstat mlx4_0 1
      
          CA: 'mlx4_0'
          Port 1:
          State: Active
          Physical state: LinkUp
          Rate: 40 (FDR10)
          Base lid: 11
          LMC: 0
          SM lid: 24
          Capability mask: 0x02514868
          Port GUID: 0x0002c903002e65d1
          Link layer: InfiniBand
      
      Extended Port Query (EPI) vendor mad timeouts before the patch:
      
          # smpquery MEPI 11 -d
      
          ibwarn: [4196] smp_query_via: attr 0xff90 mod 0x0 route Lid 11
          ibwarn: [4196] _do_madrpc: retry 1 (timeout 1000 ms)
          ibwarn: [4196] _do_madrpc: retry 2 (timeout 1000 ms)
          ibwarn: [4196] _do_madrpc: timeout after 3 retries, 3000 ms
          ibwarn: [4196] mad_rpc: _do_madrpc failed; dport (Lid 11)
          smpquery: iberror: [pid 4196] main: failed: operation EPI: ext port info query failed
      
      EPI query works OK with the patch:
      
          # smpquery MEPI 11 -d
      
          ibwarn: [6548] smp_query_via: attr 0xff90 mod 0x0 route Lid 11
