Customer running an application that issues SYNCHRONIZE_CACHE calls
directly noticed the broad stroke of the current implementation in the
aacraid driver resulting in multiple applications feeding I/O to the
storage causing the issuing application to stall for long periods of
time. By only waiting for the current WRITE commands, rather than all
commands, to complete; and those that are in range of the
SYNCHRONIZE_CACHE call that would associate more tightly with the
issuing application before telling the Firmware to flush it's dirty
cache, we managed to reduce the stalling. The Firmware itself still
flushes all the dirty cache associated with the array ignoring the
range, it just does so in a more timely manner.Signed-off-by: Mark Salyzyn

Wide transfers are required for every setting of PPR apart from QAS.
It seems the DV code starts at the minimum, which turns on DT and Wide
regardless of the setting of max_width. Redo the PPR and period
setting routines to respect max_width (i.e. start at period = 10 if it
is zero).This fixes bugzilla 8366

It was found by LSI that on setups with large amounts of memory
we were bouncing buffers when we did not need to. If the iscsi tcp
code touches the data buffer (or a helper does),
it will kmap the buffer. iscsi_tcp also does not interact with hardware,
so it does not have any hw dma restrictions. This patch sets the bounce
buffer settings for our device queue so buffers should not be bounced
because of a driver limit.Signed-off-by: Mike Christie

The recent 9p commit: bd238fb431f31989898423c8b6496bc8c4204a86 that
supposedly only moved files also introduced a new 9p sysctl interface
that did not properly register it's sysctl binary numbers.And since it was only for debugging clearly did not need a binary fast
path in any case. So this patch just remove the binary numbers.See Documentation/sysctl/ctl_unnumbered.txt for more details.
While I was at it I cleaned up the sysctl initializers a little as
well so there is less to read.Cc: Latchesar Ionkov
