CVS commit: src/sys



Module Name:    src
Committed By:   ad
Date:           Fri Oct 13 18:48:56 UTC 2023

Modified Files:
        src/sys/kern: kern_condvar.c kern_sleepq.c
        src/sys/rump/librump/rumpkern: locks.c locks_up.c
        src/sys/sys: condvar.h lwp.h

Log Message:
Add cv_fdrestart() (better name suggestions welcome):

Like cv_broadcast(), but make any LWPs that share the same file descriptor
table as the caller return ERESTART when resuming.  Used to dislodge LWPs
waiting for I/O that prevent a file descriptor from being closed, without
upsetting access to the file (not descriptor) made from another direction.
