Subject: [PATCH 26/30] reset dl_load_write_lock after forking
The patch in this Bugzilla entry was requested by a customer:
https://www.sourceware.org/bugzilla/show_bug.cgi?id=19282
The __libc_fork() code reset dl_load_lock, but it also needed to reset
dl_load_write_lock. The patch has not yet been integrated upstream.
