[PATCH 07/13] module: mark module_mutex static

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Except for two lockdep asserts module_mutex is only used in module.c.
Remove the two asserts given that the functions they are in are not
exported and just called from the module code, and mark module_mutex
static.
