+Subject: [PATCH] build-sys: fix option handling
+
+Explicit --enable-pidwait wasn't setting ENABLE_PIDWAIT. Fix that by
+moving the ENABLE_PIDWAIT handling outside of AC_ARG_ENABLE.
+
+While here, fix all the other AC_* calls to correctly set enable_XYZ or
+with_XYZ to avoid other problems, otherwise they'd be left unset if
+enabled rather than set to the correct value (yes or no).

+Subject: [PATCH] pgrep: Fix pidwait only waiting for half of specified
+ processes
+
+The pidwait command currently waits for only half of the given
+processes. This happens because when a monitored process terminates, its
+pidfd can generate two events: one for the process exiting (EPOLLIN),
+and another for it being reaped by its parent (EPOLLIN or EPOLLHUP). The
+existing code increments its completion counter for every event
+returned, causing it to count each process termination twice and exit
+prematurely.
+
+This fix tells the kernel to deactivate the file descriptor after the
+first event (process exit) is delivered, and prevents any subsequent
+events from being processed for the same pidfd.
