Hi all, Maybe someone here knows better.
I have several user-mode processes using shared mmap. There can be several reader processes and only one writer. Readers access the shared region frequently, writer seldom. Naturally, multi-reader/single-writer locks works best. I tried this with futex on 2.6.9-42.EL. However, if one of the processes is killed/exits, the lock doesn't get released. I can trap the signal to release the lock, but not all signals like kill. Anyway I can achieve this without a potential deadlock?
