kernel/hung_task.c: set some hung_task.c variables storage-class-specifier to static
Commit Message
smatch reports several warnings
kernel/hung_task.c:31:19: warning:
symbol 'sysctl_hung_task_check_count' was not declared. Should it be static?
kernel/hung_task.c:50:29: warning:
symbol 'sysctl_hung_task_check_interval_secs' was not declared. Should it be static?
kernel/hung_task.c:52:19: warning:
symbol 'sysctl_hung_task_warnings' was not declared. Should it be static?
kernel/hung_task.c:75:28: warning:
symbol 'sysctl_hung_task_panic' was not declared. Should it be static?
These variables are only used in hung_task.c, so they should be static
