Subject: Cleaned up MUTEX() #define
X-Git-Tag: spl-0.6.0-rc7~36
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f5e76dea03453c72fb46ad90dd2e01c73b70654f;p=spl

Cleaned up MUTEX() #define

The old define assumed a specific layout of the kmutex_t struct. This
patch makes the macro independent from the actual struct layout.
