      lib/scatterlist: do not re-write gfp_flags in __sg_alloc_table() · e04f2283
      Mandeep Singh Baines authored
      
      
      We are seeing a lot of sg_alloc_table allocation failures using the new
      drm prime infrastructure.  We isolated the cause to code in
      __sg_alloc_table that was re-writing the gfp_flags.
      
      There is a comment in the code that suggest that there is an assumption
      about the allocation coming from a memory pool.  This was likely true
      when sg lists were primarily used for disk I/O.

      cpu: rewrite cpu-notifier-error-inject module · f5a9f52e
      Akinobu Mita authored
      
      
      Rewrite existing cpu-notifier-error-inject module to use debugfs based new
      framework.
      
      This change removes cpu_up_prepare_error and cpu_down_prepare_error module
      parameters which were used to specify error code to be injected.  We could
      keep these module parameters for backward compatibility by module_param_cb
      but it seems overkill for this module.
      
      This provides the ability to inject artifical errors to CPU notifier chain
      callbacks.  It is controlled through debugfs interface under
      /sys/kernel/debug/notifier-error-inject/cpu
      
      If the notifier call chain should be failed with some events notified,
      write the error code to "actions/<notifier event>/error".
      
      Example1: inject CPU offline error (-1 == -EPERM)
      
      	# cd /sys/kernel/debug/notifier-error-inject/cpu
      	# echo -1 > actions/CPU_DOWN_PREPARE/error
      	# echo 0 > /sys/devices/system/cpu/cpu1/online
      	bash: echo: write error: Operation not permitted
      
      Example2: inject CPU online error (-2 == -ENOENT)
      
      	# cd /sys/kernel/debug/notifier-error-inject/cpu
      	# echo -2 > actions/CPU_UP_PREPARE/error
      	# echo 1 > /sys/devices/system/cpu/cpu1/online
      	bash: echo: write error: No such file or directory

      fault-injection: notifier error injection · 8d438288
      Akinobu Mita authored
      
      
      This patchset provides kernel modules that can be used to test the error
      handling of notifier call chain failures by injecting artifical errors to
      the following notifier chain callbacks.
      
       * CPU notifier
       * PM notifier
       * memory hotplug notifier
       * powerpc pSeries reconfig notifier
      
      Example: Inject CPU offline error (-1 == -EPERM)
      
        # cd /sys/kernel/debug/notifier-error-inject/cpu
        # echo -1 > actions/CPU_DOWN_PREPARE/error
        # echo 0 > /sys/devices/system/cpu/cpu1/online
        bash: echo: write error: Operation not permitted
      
      The patchset also adds cpu and memory hotplug tests to
      tools/testing/selftests These tests first do simple online and offline
      test and then do fault injection tests if notifier error injection
      module is available.
      
      This patch:
      
      The notifier error injection provides the ability to inject artifical
      errors to specified notifier chain callbacks.  It is useful to test the
      error handling of notifier call chain failures.
      
      This adds common basic functions to define which type of events can be
      fail and to initialize the debugfs interface to control what error code
      should be returned and which event should be failed.

      c/r: fcntl: add F_GETOWNER_UIDS option · 1d151c33
      Cyrill Gorcunov authored
      
      
      When we restore file descriptors we would like them to look exactly as
      they were at dumping time.
      
      With help of fcntl it's almost possible, the missing snippet is file
      owners UIDs.
      
      To be able to read their values the F_GETOWNER_UIDS is introduced.
      
      This option is valid iif CONFIG_CHECKPOINT_RESTORE is turned on, otherwise
      returning -EINVAL.

      resource: make sure requested range is included in the root range · 65fed8f6
      Octavian Purdila authored
      
      
      When the requested range is outside of the root range the logic in
      __reserve_region_with_split will cause an infinite recursion which will
      overflow the stack as seen in the warning bellow.
      
      This particular stack overflow was caused by requesting the
      (100000000-107ffffff) range while the root range was (0-ffffffff).  In
      this case __request_resource would return the whole root range as
      conflict range (i.e.  0-ffffffff).  Then, the logic in
      __reserve_region_with_split would continue the recursion requesting the
      new range as (conflict->end+1, end) which incidentally in this case
      equals the originally requested range.
      
      This patch aborts looking for an usable range when the request does not
      intersect with the root range.  When the request partially overlaps with
      the root range, it ajust the request to fall in the root range and then
      continues with the new request.
      
      When the request is modified or aborted errors and a stack trace are
      logged to allow catching the errors in the upper layers.

      include/linux/aio.h: cpp->C conversions · f7e1becb
      Andrew Morton authored
      
      
      Convert init_sync_kiocb() from a nasty macro into a nice C function.  The
      struct assignment trick takes care of zeroing all unmentioned fields.
      Shrinks fs/read_write.o's .text from 9857 bytes to 9714.
      
      Also demacroize is_sync_kiocb() and aio_ring_avail().  The latter fixes an
      arg-referenced-multiple-times hand grenade.

      pps: return PTR_ERR on error in device_create · 668f06b9
      Emil Goode authored
      
      
      We should return PTR_ERR if the call to the device_create function fails.
      Without this patch we instead return the value from a successful call to
      cdev_add if the call to device_create fails.
