anymore do this if we fail to set size.
The whole lookup procedure should be done in a smarter fashion,
but this is the quickie fix to get things working again.
against the directory name of the makefile being processed.
Shortens a lot of pathnames (especially in pkgsrc) and significantly
reduces the number of duplicate entries in .MAKE.MAKEFILES
are first processed, not for every line of every loop inside the file.
When (attempting) to check for duplicate names, use the spaces between names
as separators rather than using strstr() - which is slow and wont find
duplicates after an incorect early match.
However the duplicate check is rather broken (especially for pkgsrc) where
names like ../../devel/atk/../../devel/glib2/../../devel/gettext-lib/ \
../../devel/gettext-lib/../../mk/buildlink3/../../mk/bsd.prefs.mk
which need (some form of) realpath() processing.
'cd pkgsrc/xaa/gtk2; make show-var VARNAME=.MAKE.MAKEFILES' shows the problem.
- uiomove: don't bother dropping kernel_lock if moving less than 1k.
- Catch up with vfsops reference counting changes (for LKMs).
- Add crit_enter()/crit_exit(). These bound critical sections in which
kernel preemption is to be disabled. Better names welcome.
use UVM_UNKNOWN_OFFSET in the call to uvm_map_prepare.
This fixes a '"panic: malloc: out of space in kmem_map" when it's not
really' testcase of mine, and one reported to me by chuq. This is likely
to fix PR/35587 as well.
Looks/seems fine to me from chuq and yamt. Thanks.
- G/C spinlockmgr() and simple_lock debugging.
- Always include the kernel_lock functions, for LKMs.
- Slightly improved subr_lockdebug code.
- Keep sizeof(struct lock) the same if LOCKDEBUG.
interacts with the userspace file server:
* since the kernel-user communication is not purely request-response
anymore (hasn't been since 2006), try to rename some "request" to
"message". more similar mangling will take place in the future.
* completely rework how messages are allocated. previously most of
them were borrowed from the stack (originally *all* of them),
but now always allocate dynamically. this makes the structure
of the code much cleaner. also makes it possible to fix a
locking order violation. it enables plenty of future enhancements.
* start generalizing the transport interface to be independent of puffs
* move transport interface to read/write instead of ioctl. the
old one had legacy design problems, and besides, ioctl's suck.
implement a very generic version for now; this will be
worked on later hopefully some day reaching "highly optimized".
* implement libpuffs support behind existing library request
interfaces. this will change eventually (I hate those interfaces)
