      xfs: ensure committed is initialized in xfs_trans_roll · cc07eed8
      Eric Sandeen authored
      __xfs_trans_roll() can return without setting the
      *committed argument; this was a problem for xfs_bmap_finish():
      
              int       committed;/* xact committed or not */
      ...
              error = __xfs_trans_roll(tp, ip, &committed);
              if (error) {
      ...
                      if (committed) {
      
      and we tested an uninitialized "committed" variable on the
      error path.  No caller is preserving "committed" state across
      calls to __xfs_trans_roll(), so just initialize committed inside
      the function to avoid future errors like this.

      xfs: borrow indirect blocks from freed extent when available · d34999c9
      Brian Foster authored
      xfs_bmap_del_extent() handles extent removal from the in-core and
      on-disk extent lists. When removing a delalloc range, it updates the
      indirect block reservation appropriately based on the removal. It
      currently enforces that the new indirect block reservation is less than
      or equal to the original. This is normally the case in all situations
      except for in certain cases when the removed range creates a hole in a
      single delalloc extent, thus splitting a single delalloc extent in two.
      
      It is possible with small enough extents to split an indlen==1 extent
      into two such slightly smaller extents. This leaves one extent with 0
      indirect blocks and leads to assert failures in other areas (e.g.,
      xfs_bunmapi() if the extent happens to be removed).
      
      Update the indlen distribution code to steal blocks from the deleted
      extent, if necessary, to satisfy the worst case total indirect
      reservation for the new extents. This is safe as the caller does not
      update the fdblocks counters until the extent is removed. Blocks stolen
      in this manner simply remain accounted as allocated, having ownership
      transferred from the data extent to an indirect reservation.
      
      As a precaution, fall back to the original reservation algorithm if the
      new indlen requirement is not met and warn if we end up with extents
      without any reservation at all to detect this more easily in the future.

      xfs: refactor delalloc indlen reservation split into helper · a9bd24ac
      Brian Foster authored
      The delayed allocation indirect reservation splitting code is not
      sufficient in some cases where a delalloc extent is split in two. In
      preparation for enhancements to this code, refactor the current indlen
      distribution algorithm into a new helper function.

      xfs: update freeblocks counter after extent deletion · b2706a05
      Brian Foster authored
      xfs_bunmapi() currently updates the fdblocks counter, unreserves quota,
      etc. before the extent is deleted by xfs_bmap_del_extent(). The function
      has problems dividing up the indirect reserved blocks for scenarios
      where a single delalloc extent is split in two. Particularly, there
      aren't always enough blocks reserved for multiple extents in a single
      extent reservation.
      
      The solution to this problem is to allow the extent removal code to
      steal from the deleted extent to meet indirect reservation requirements.
      Move the block of code in xfs_bmapi() that updates the fdblocks counter
      to after the call to xfs_bmap_del_extent() to allow the codepath to
      update the extent record before the free blocks are accounted. Also,
      reshuffle the code slightly so the delalloc accounting occurs near the
      xfs_bmap_del_extent() call to provide context for the comments.

      xfs: debug mode forced buffered write failure · 801cc4e1
      Brian Foster authored
      Add a DEBUG mode-only sysfs knob to enable forced buffered write
      failure. An additional side effect of this mode is brute force killing
      of delayed allocation blocks in the range of the write. The latter is
      the prime motiviation behind this patch, as userspace test
      infrastructure requires a reliable mechanism to create and split
      delalloc extents without causing extent conversion.
      
      Certain fallocate operations (i.e., zero range) were used for this in
      the past, but the implementations have changed such that delalloc
      extents are flushed and converted to real blocks, rendering the test
      useless.

           given policy object is the last element of a list instead of open
           coding that in a clumsy way (Gautham R Shenoy).
      
         - Fix compiler warnings in the pxa2xx and cpufreq-dt cpufreq drivers
           (Arnd Bergmann).
      
         - Fix two locking issues and clean up a comment in the generic power
           domains framework (Ulf Hansson, Marek Szyprowski, Moritz Fischer).
      
         - Fix the error code path of one function in the ACPI-based PCI
           hotplug framework (ACPIPHP) that forgets to release a lock acquired
           previously (Insu Yun).
      
         - Drop the ACPI backlight blacklist entry for Dell Inspiron 5737 that
           is not necessary any more (Hans de Goede).
      
         - Clean up the top-level PM Kconfig to stop requiring APM emulation
           to depend on PM which in fact isn't necessary (Arnd Bergmann)"

      This reverts commit 14e46e04.
      
      This ends up doing sysfs operations from deep in balance (where we
      should be GFP_NOFS) and under heavy balance load, we're making races
      against sysfs internals.
      
      Revert it for now while we figure things out.

      serial: 8250_pci: Add Intel Broadwell ports · 6c55d9b9
      Mika Westerberg authored
      Some recent (early 2015) macbooks have Intel Broadwell where LPSS UARTs are
      PCI enumerated instead of ACPI. The LPSS UART block is pretty much same as
      used on Intel Baytrail so we can reuse the existing Baytrail setup code.
      
      Add both Broadwell LPSS UART ports to the list of supported devices.
