- Consistently refer to rmlocks as "read-mostly locks".
- Relate rmlocks to rwlocks rather than sx locks since they are closer to
rwlocks.
- Add a separate paragraph on sleepable read-mostly locks contrasting them
with "normal" read-mostly locks.
- The flag passed to rm_init_flags() to enable recursion for readers is
RM_RECURSE, not LO_RECURSABLE.
- Fix the description for RM_RECURSE (it allows readers to recurse, not
writers).
- Explicitly note that rm_try_rlock() honors RM_RECURSE.
- Fix some minor grammar nits.
CAM_DEBUG_CDB, CAM_DEBUG_PERIPH and CAM_DEBUG_PROBE) by default.
List of these flags can be modified with CAM_DEBUG_COMPILE kernel option.
CAMDEBUG kernel option still enables all possible debug, if not overriden.
Additional 50KB of kernel size is a good price for the ability to debug
problems without rebuilding the kernel. In case where size is important,
debugging can be compiled out by setting CAM_DEBUG_COMPILE option to 0.
stages (build-tools, cross-tools, etc) of the build, so we can detect in
bsd.*.mk whether to pass compiler-specific flags to ${CC}.
In particular, this commit will allow using WITH_CLANG_IS_CC when the
base compiler is still gcc, and when ${CC}, ${CXX} and ${CPP} are left
at their defaults. The early stages will then be built using gcc, and
no clang-specific flags will be passed to it. The later stages will be
built as usual.
The EARLY_BUILD define can also serve other uses, such as building the
world stage C++ executables with libc++ instead of libstdc++: during the
early build stages, we cannot assume libc++ is already available, so we
must still build with libstdc++ at that time.

Revamp the CAM enclosure services driver.
This updated driver uses an in-kernel daemon to track state changes and
publishes physical path location information\for disk elements into the
CAM device database.
