      Linus Torvalds authored
      Pull block IO fixes from Jens Axboe:
       "After merge window, no new stuff this time only a collection of neatly
        confined and simple fixes"
      
      * 'for-3.12/core' of git://git.kernel.dk/linux-block:
        cfq: explicitly use 64bit divide operation for 64bit arguments
        block: Add nr_bios to block_rq_remap tracepoint
        If the queue is dying then we only call the rq->end_io callout. This leaves bios setup on the request, because the caller assumes when the blk_execute_rq_nowait/blk_execute_rq call has completed that the rq->bios have been cleaned up.
        bio-integrity: Fix use of bs->bio_integrity_pool after free
        blkcg: relocate root_blkg setting and clearing
        block: Convert kmalloc_node(...GFP_ZERO...) to kzalloc_node(...)
        block: trace all devices plug operation

      cfq: explicitly use 64bit divide operation for 64bit arguments · f3cff25f
      Anatol Pomozov authored
      'samples' is 64bit operant, but do_div() second parameter is 32.
      do_div silently truncates high 32 bits and calculated result
      is invalid.
      
      In case if low 32bit of 'samples' are zeros then do_div() produces
      kernel crash.

      CacheFiles: Don't try to dump the index key if the cookie has been cleared · 509bf24d
      David Howells authored
      Don't try to dump the index key that distinguishes an object if netfs
      data in the cookie the object refers to has been cleared (ie.  the
      cookie has passed most of the way through
      __fscache_relinquish_cookie()).
      
      Since the netfs holds the index key, we can't get at it once the ->def
      and ->netfs_data pointers have been cleared - and a NULL pointer
      exception will ensue, usually just after a:
      
      	CacheFiles: Error: Unexpected object collision
      
      error is reported.

      CacheFiles: Fix memory leak in cachefiles_check_auxdata error paths · 607566ae
      Josh Boyer authored
      In cachefiles_check_auxdata(), we allocate auxbuf but fail to free it if
      we determine there's an error or that the data is stale.
      
      Further, assigning the output of vfs_getxattr() to auxbuf->len gives
      problems with checking for errors as auxbuf->len is a u16.  We don't
      actually need to set auxbuf->len, so keep the length in a variable for
      now.  We shouldn't need to check the upper limit of the buffer as an
      overflow there should be indicated by -ERANGE.
      
      While we're at it, fscache_check_aux() returns an enum value, not an
      int, so assign it to an appropriately typed variable rather than to ret.
