Now that musl toolchains depend on netbsd-queue package, a implementation of sys/queue.h will always be available in the staging directory, so we can remove the patch that adds a local sys/queue.h implementation.

Subject: [PATCH] Add missing rwlock_unlocks in xprt_register
|
|
|
|
It looks like in b2c9430f46c4ac848957fb8adaac176a3f6ac03f when svc_run
|
|
switched to poll, an early return was added, but the rwlock was not
|
|
unlocked.
|
|
|
|
I observed that rpcbind built against libtirpc-1.0.1 would handle only
|
|
one request before hanging, and tracked it down to a missing
|
|
rwlock_unlock here.
|
|
|
|
Fixes: b2c9430f46c4 ('Use poll() instead of select() in svc_run()')
