X-Git-Tag: v2.6.35-rc4~45^2
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=b70e4f0529c089b00d0a6da13106db4de1ada4c7;p=linux.git

tracing: Fix undeclared ENOSYS in include/linux/tracepoint.h

The header file include/linux/tracepoint.h may be included without
include/linux/errno.h and then the compiler will fail on building for
undelcared ENOSYS. This patch fixes this problem via including <linux/errno.h>
to include/linux/tracepoint.h.
