| |
Hi all
In fs/*.c, many functions manually set the task state directly accessing current->state, or with a macro, kind of inconsistently. This patch changes all of them to use [__]set_current_state().
Changelog:
Take 3:
- Port to 2.5.64
- Port to 2.5.57
- Use safe set_current_state() instead of __set... in exec.c:de_thread()
Take 2:
- Added feedback from Robert Love regarding usage of __set_current_thread() vs. set_current_thread() to avoid race conditions related to memory flush.
- Use cond_resched() in namei.c:do_follow_link().
Take 1:
- Ported forward to 2.5.52
