           Version: 24
         Component: golang
          Severity: high

Description of problem:
The epoll_event structure is defined incorrectly which causes the failures in
fsnotify.

Version-Release number of selected component (if applicable):
golang-1.6-1

How reproducible:
rebuild golang-github-go-fsnotify-fsnotify on powerpc

Actual results:

Expected results:
it should be built fine on ppc64

Additional info:
this issue is fixed in golang upstream. I also backported the fix for current
golang-1.6 in fedora and confirmed that
it fixes this epoll issue. The golang-github-go-fsnotify-fsnotify also built
fine with new fixed golang.
The backported fix will be attached in next comment
