The patch titled
dev_vdbg(), available with -DVERBOSE_DEBUG
has been removed from the -mm tree. Its filename was
dev_vdbg-available-with-dverbose_debug.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: dev_vdbg(), available with -DVERBOSE_DEBUG
From: David Brownell <david-b@xxxxxxxxxxx>
This defines a dev_vdbg() call, which is enabled with -DVERBOSE_DEBUG.
When enabled, dev_vdbg() acts just like dev_dbg(). When disabled, it is a
NOP ... just like dev_dbg() without -DDEBUG. The specific code was moved
out of a USB patch, but lots of drivers have similar support.
That is, code can now be written to use an additional level of debug
output, selected at compile time. Many driver authors have found this
idiom to be very useful. A typical usage model is for "normal" debug
messages to focus on fault paths and not be very "chatty", so that those
messages can be left on during normal operation without much of a
performance or syslog load. On the other hand "verbose" messages would be
noisy enough that they wouldn't normally be enabled; they might even affect
timings enough to change system or driver behavior.
