Subject: [PATCH] mm/thp: Drop unused trace events hugepage_[invalidate|splitting]
Date: Fri,  7 Jan 2022 14:35:51 +0530	[thread overview]
Message-ID: <1641546351-15109-1-git-send-email-anshuman.khandual@arm.com> (raw)

The trace events hugepage_[invalidate|splitting], were added via the commit
9e813308a5c1 ("powerpc/thp: Add tracepoints to track hugepage invalidate").
Afterwards their call sites i.e trace_hugepage_[invalidate|splitting] were
just dropped off, leaving these trace points unused.
