The quilt patch titled Subject: selftests/mm: compaction_test: fix incorrect write of zero to nr_hugepages has been removed from the -mm tree. Its filename was selftests-mm-compaction_test-fix-incorrect-write-of-zero-to-nr_hugepages.patch
This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Currently, the test tries to set nr_hugepages to zero, but that is not actually done because the file offset is not reset after read(). Fix that using lseek().
