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

2. Move list of signal actions from the task TCB to the task group.  Signal handlers are a property of the entire task group and not of individual threads in the group.  I know, I preferred it the other way too but this is more compliant with POSIX.
