[Linux-kselftest-mirror] [PATCH] tools/testing: Fix trailing semicolon

by Luis de Bethencourt

The trailing semicolon is an empty statement that does no operation. Removing it since it doesn't do anything.

[Linux-kselftest-mirror] [PATCH] kselftest: fix OOM in memory compaction test

by Arnd Bergmann

Running the compaction_test sometimes results in out-of-memory failures. When I debugged this, it turned out that the code to reset the number of hugepages to the initial value is simply broken since we write into an open sysctl file descriptor multiple times without seeking back to the start. Adding the lseek here fixes the problem.
