| Subject: [PATCH] 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. |
