      vfs: add missing virtual cache flush after editing partial pages · 6d283dba
      Linus Torvalds authored
      Andrew Morton pointed this out a month ago, and then I completely forgot
      about it.
      If we read a partial last page of a block device, we will zero out the
      end of the page, but since that page can then be mapped into user space,
      we should also make sure to flush the cache on architectures that have
      virtual caches.  We have the flush_dcache_page() function for this, so
      use it.
      Now, in practice this really never matters, because nobody sane uses
      virtual caches to begin with, and they largely exist on old broken RISC
      And even if you did run on one of those obsolete CPU's, the whole "mmap
      and access the last partial page of a block device" behavior probably
      doesn't actually exist.  The normal IO functions (read/write) will never
      see the zeroed-out part of the page that migth not be coherent in the
      cache, because they honor the size of the device.
      So I'm marking this for stable (3.7 only), but I'm not sure anybody will
      ever care.

      tracing: Fix regression of trace_pipe · 250bfd3d
      Liu Bo authored
      Commit 0fb9656d "tracing: Make tracing_enabled be equal to tracing_on"
      changes the behaviour of trace_pipe, ie. it makes trace_pipe return if
      we've read something and tracing is enabled, and this means that we have
      to 'cat trace_pipe' again and again while running tests.
      IMO the right way is if tracing is enabled, we always block and wait for
      ring buffer, or we may lose what we want since ring buffer's size is limited.

      be2net: fix unconditionally returning IRQ_HANDLED in INTx · d0b9cec3
      Sathya Perla authored
      commit e49cc34f
       introduced an unconditional IRQ_HANDLED return in be_intx()
      to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel
      from detecting interrupt storms due to broken HW.
      The BE2/Lancer HW issues are:
      1) In Lancer, there is no means for the driver to detect if the interrupt
      belonged to device, other than counting and notifying events.
      2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler
      to be called multiple times till the de-assert happens.
      3) In BE2, we see an occasional interrupt even when EQs are unarmed.
      Issue (1) can cause the notified events to be orphaned, if NAPI was already
      This patch fixes this issue by scheduling NAPI only if it is not scheduled
      already. Doing this also takes care of possible events_get() race that may be
      caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first
      time zero events are detected.
      (Thanks Ben H. for the feedback and suggestions.)
