kib 2007-02-01 13:29:27 UTC FreeBSD src repository Modified files: sys/compat/linux linux_emul.c Log: No need to synchronize linux_schedtail with linux_proc_init. p->p_emuldata is properly initialized in the time when the child can run. Do not set p->p_emuldata to NULL when the process is exiting. It does not make any sense and only costs 2 mutex operations. Do not lock emul_data to unlock it on the very next line. Comment on possible race while there. Reparent all procs that are part of a threading group but not its leaders to init and SIGCHLD init to finish the zombies off. This fixes zombies left after opera's exit. [1] There is no need to lock p_em in the linux_proc_init CLONE_THREAD case because the process cannot change the address of the p_em->shared because its currently running this code path. Move assigning of em->shared outside emul_shared_lock. Noticed by: Scott Robbins <scottro@nyc.rr.com> [1] Submitted by: rdivacky Revision Changes Path 1.14 +28 -26 src/sys/compat/linux/linux_emul.c
