      Fix barrier fail detection in XFS · 73f6aa4d
      Christoph Hellwig authored
      Currently we disable barriers as soon as we get a buffer in xlog_iodone
      that has the XBF_ORDERED flag cleared.  But this can be the case not only
      for buffers where the barrier failed, but also the first buffer of a
      split log write in case of a log wraparound.  Due to the disabled
      barriers we can easily get directory corruption on unclean shutdowns.
      So instead of using this check add a new buffer flag for failed barrier
      writes.
      
      This is a regression vs 2.6.26 caused by patch to use the right macro
      to check for the ORDERED flag, as we previously got true returned for
      every buffer.
      
      Thanks to Toei Rei for reporting the bug.

      PnP: move pnpacpi/pnpbios_init to after PCI init · ed458df4
      Linus Torvalds authored
      We already did that a long time ago for pnp_system_init, but
      pnpacpi_init and pnpbios_init remained as subsys_initcalls, and get
      linked into the kernel before the arch-specific routines that finalize
      the PCI resources (pci_subsys_init).
      
      This means that the PnP routines would either register their resources
      before the PCI layer could, or would be unable to check whether a PCI
      resource had already been registered.  Both are problematic.
      
      I wanted to do this before 2.6.27, but every time we change something
      like this, something breaks.  That said, _every_ single time we trust
      some firmware (like PnP tables) more than we trust the hardware itself
      (like PCI probing), the problems have been worse.

      dm crypt: avoid unnecessary wait when splitting bio · 933f01d4
      Milan Broz authored
      Don't wait between submitting crypt requests for a bio unless
      we are short of memory.
      
      There are two situations when we must split an encrypted bio:
        1) there are no free pages;
        2) the new bio would violate underlying device restrictions
      (e.g. max hw segments).
      
      In case (2) we do not need to wait.
      
      Add output variable to crypt_alloc_buffer() to distinguish between
      these cases.

      Move the initialisation of ctx->pending into one place, at the
      start of crypt_convert().
      
      Introduce crypt_finished to indicate whether or not the encryption
      is finished, for use in a later patch.

      dm crypt: fix async inc_pending · 4e594098
      Milan Broz authored
      The pending reference count must be incremented *before* the async work is
      queued to another thread, not after.  Otherwise there's a race if the
      work completes and decrements the reference count before it gets incremented.

      dm crypt: move dec_pending on error into write_io_submit · 6c031f41
      Milan Broz authored
      Make kcryptd_crypt_write_io_submit() responsible for decrementing
      the pending count after an error.
      
      Also fixes a bug in the async path that forgot to decrement it.

      Make the caller reponsible for incrementing the pending count before calling
      kcryptd_crypt_write_io_submit() in the non-async case to bring it into line
      with the async case.

      dm raid1: kcopyd should stop on error if errors handled · f7c83e2e
      Jonathan Brassow authored
      dm-raid1 is setting the 'DM_KCOPYD_IGNORE_ERROR' flag unconditionally
      when assigning kcopyd work.  kcopyd is responsible for copying an
      assigned section of disk to one or more other disks.  The
      'DM_KCOPYD_IGNORE_ERROR' flag affects kcopyd in the following way:
      
      When not set:
      kcopyd will immediately stop the copy operation when an error is
      encountered.
      
      When set:
      kcopyd will try to proceed regardless of errors and try to continue
      copying any remaining amount.
      
      Since dm-raid1 tracks regions of the address space that are (or
      are not) in sync and it now has the ability to handle these
      errors, we can safely enable this optimization.  This optimization
      is conditional on whether mirror error handling has been enabled.
