[PATCH] chdir-notify: UNLEAK registrated callback entries

From: René Scharfe <l.s.r@web.de>
Date: Nov 14, 2020, 21:40 UTC
Message-ID: <8a9cf9ba-f615-3ff5-8d35-c24c22d5d859@web.de>

chdir_notify_register() allows registering functions to notify when chdir() is called. There is no way to unsubscribe or shut this mechanism down, so these entries are present until the program ends.

Valgrind reports allocations for these registrations as "possibly lost", probably because it doesn't see through list.h's offsetof tricks. Annotate them using UNLEAK, which causes Valgrind to report them as "still reachable" instead.
