nor declared in any installed header file, and it probably should not
be externally exposed.) Related to PR 44183, closes PR 44186.
external/lib/Makefile and crypto/external/lib/Makefile, replacing
them all with SUBDIRs directly from lib/Makefile.
compat/compatsubdirs.mk becomes simpler now, as everything is built
from lib/Makefile, meaning all the libraries will now be built under
compat so update the set lists to account for that.
skip entries, print (null), run off the end of the array, or occasionally
receive SIGSEGV, and now will, hopefully at least, do none of that.
Based in part on the patch in PR 44183 from Sergio Acereda; I also
did some tidyup and fixed it to print top-to-bottom first like ls(1).
is done in rumpuser for simplicity, since on the kernel side things
we assume we have only one pointer of space). As a side-effect,
we can no longer know if the current thread is holding on to a
mutex locked without curlwp context (basically all mutexes inited
outside of mutex_init()). The only thing that called rumpuser_mutex_held()
for a non-kmutex was the giant lock. So, instead implement recursive
locking for the giant lock in the rump kernel and get rid of the
now-unused recursive pthread mutex in the hypercall interface.
Also, add rump_daemonize_begin() / rump_daemonize_end() to help
with the "can't daemon() after pthread_create()" problem. Applications
could accomplish the same, but since it's such a common operation,
provide a little help.
limits. This improves syscall throughput about 2x for non-userio
syscalls (no copyin/out, e.g. getpid()) and almost 1.5x even for
things like __sysctl().
(measured for cases where the remote process is on the local machine)
XXX: if the pthread deadqueue sucks for anything which cares about
performance, why does it exist? Nuking it would make supporting
variable stack size easier.
