a9cf7250ba staging: rtl8192e: don't just print an error and continue
I was looking at how TOTAL_CAM_ENTRY is used and I saw this code.  We
print an error but continue writing "EntryNo" to a register as if it
were valid.  "EntryNo" is controlled by the user in rtl8192_ioctl() so
it definitely can be invalid.  I'm not positive what happens with the
invalid data but it can't be good.

c847020e7a staging: unisys: visornic_resume needs to mirror _serverdown_complete
Previously we simplified the serverdown function to basically turn it
into a dev_close(), but missed the analogous logic in visornic_resume()
(which is essentially the "book-end" of visornic_serverdown_complete()).
As a result, during IO partition recovery, the nic would go closed when
the IO partition went away, but would never be opened again when the IO
partition came back.

This patch changes visornic_resume() to use dev_open(), so that it once
again plays nicely with visornic_serverdown_complete().  Because
dev_open() forces us into the visornic_open() path, other logic in
visornic_resume() was no longer necessary, and lended to simplifying
visornic_resume() even more.

6483783d24 staging: unisys: visornic - correctly reset flag prior to send_enbdis()
Because devdata->enab_dis_acked is the flag used to determine whether an
enable/disable operation to the IO partition has completed, it should
always be cleared prior to initiating the operation.  The call added to
visornic_enable_with_timeout() added in this patch makes the usage there
consistent with visornic_disable_with_timeout().

6f562b2161 staging: unisys: visornic - prevent lock recursion after IO recovery
In the patch which changed the serverdown logic to by synchronous, we
were
mistakenly holding on to devdata->priv_lock in the call to
visornic_serverdown_complete(), which ultimately ended up recursively
attempting to grab the same lock via the path:

    --> dev_close
        --> visornic_close()
            --> visornic_disable_with_timeout()

176d1b9643 staging/lustre/llite: Don't set page writeback on non-dirty page
New writeback changes in 4.2-RC1 have exposed that we incorrectly
set page_writeback on a page that is being written synchronously,
which aside from this new crash (dereference of NULL inode->i_wb
from set_page_writeback) likely threw off some related page
statistics in the past.
