5ea77118aa Explicitly initialize the group tg_exitsem with sem_init(). The existing logic worked because the correct initialization value is all zero, but it is better to initialize the semaphore explicitly. Noted by Jouko Holopainen. 2016-08-10 07:38:07 -06:00

6cfe56202d Backout 3f731241cb. It is a good idea, but has some unpleasant side effect... like SYSLOG and dbg() no longer work 2016-04-18 18:55:36 -06:00
Gregory Nutt
3f731241cb fs/inode/, fs/vfs/, and sched/task/: File and socket descriptors are no longer allocated for kernel threads. They must use SYSLOG for output and the low-level psock interfaces for network I/O. This saves a little memory which might be important for small footprint configurations. 2016-04-14 10:14:38 -06:00
