Subject: [PATCH 2/3] perf trace: Add fallback definition of EFD_SEMAPHORE
|
|
Forwarded: http://mid.gmane.org/1391648435.3003.100.camel@deadeye.wl.decadent.org.uk

glibc 2.17 is missing this on sparc, despite the fact that it's
|
|
not architecture-specific.
|
|
|
|
Fixes: 49af9e93adfa ('perf trace: Beautify eventfd2 'flags' arg')
