From 922da0c58e4107fb70364e1032c8243ac8646107 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 27 Sep 2015 16:45:33 -0400 Subject: [PATCH] staging/lustre: remove wrappers for timer functions This is a simple cleanup that I did after noticing that the abstraction for the timer functions in completely pointless, and the one user (ptlrpc) can just as well call the native Linux functions. For good measure, this also removes the empty libcfs_arch_init() and libcfs_arch_cleanup() functions that are defined in the same file.
