| H A D | lockf.h | diff 192685 Sun May 24 12:55:28 MDT 2009 kib The advisory lock may be activated or activated and removed during the sleep waiting for conditions when the lock may be granted. To prevent lf_setlock() from accessing possibly freed memory, add reference counting to the struct lockf_entry. Bump refcount around the sleep. Make lf_free_lock() return non-zero when structure was freed, and use this after the sleep to return EINTR to the caller. The error code might need a clarification, but we cannot return success to usermode, since the lock is not owned anymore. Reviewed by: dfr Tested by: pho MFC after: 1 month |
