[PATCH 7/10] Rename {alloc,free}_thread_info to {alloc,free}_thread_stack

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

 



This does a global rename of alloc_thread_info/free_thread_info to
alloc_thread_stack/free_thread_stack. This reflects what these functions
really do, the thread_info part is only a small part of the stack (and
possibly it's even somewhere else).
