Subject: [patch 033/143] mm: huge_memory: debugfs for file-backed THP split
Date: Tue, 04 May 2021 18:34:26 -0700 [thread overview]
Message-ID: <20210505013426.W69xzdab4%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210504183219.a3cc46aee4013d77402276c5@linux-foundation.org>
From: Zi Yan <ziy@nvidia.com>
Subject: mm: huge_memory: debugfs for file-backed THP split
Further extend <debugfs>/split_huge_pages to accept
"<path>,<pgoff_start>,<pgoff_end>" for file-backed THP split tests since
tmpfs may have file backed by THP that mapped nowhere.
Update selftest program to test file-backed THP split too.
