[PATCH] tty: make __proc_set_tty static
The aim of this patch set is to start wrapping up the struct pid conversions. As such this patchset culminates with the removal of kill_pg, kill_pg_info, __kill_pg_info, do_each_task_pid, and while_each_task_pid. kill_proc, daemonize, and kernel_thread are still in my sights but there is still work to get to them. The first three are basic cleanups around disassociate_ctty, while working on converting it I found several issues. tty_old_pgrp can be a tricky concept to wrap your head around. 1 tty: Make __proc_set_tty static. 2 tty: Clarify disassociate_ctty 3 tty: Fix the locking for signal->session in disassociate_ctty These just stop using the old helper functions. 4 signal: Use kill_pgrp not kill_pg in the sunos compatibility code. 5 signal: Rewrite kill_something_info so it uses newer helpers. Then the grind to convert the tty layer and all of it's helper functions to struct pid. 6 pid: Make session_of_pgrp use struct pid instead of pid_t. 7 pid: Use struct pid for talking about process groups in exit.c 8 pid: Replace is_orphaned_pgrp with is_current_pgrp_orphaned 9 tty: Update the tty layer to work with struct pid. A final helper function update. 10 pid: Replace do/while_each_task_pid with do/while_each_pid_task And the removal of the functions that are now unused. 11 pid: Remove now unused do_each_task_pid and while_each_task_pid 12 pid: Remove the now unused kill_pg kill_pg_info and __kill_pg_info All of these should be fairly simple and to the point. This patch: Currently all users of __proc_set_tty are in tty_io.c so make the function static. Signed-off-by: Eric W.
