X-Git-Tag: 2.4.92~13
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=1c9d076b8f3b8d46bfcefe82a789b57d069b5857

LU-2675 cleanup: define sparse annotations for libcfs

Add empty definitions for the sparse checker annotations (__user,
__kernel, __safe, ...) defined by the kernel. This will allow these
annotations to be used in files common to kernel modules and libcfs.
