userfaultfd: selftest: vm: allow to build in vm/ directory
[ Upstream commit 46aa6a302b53f543f8e8b8e1714dc5e449ad36a6 ]
linux/tools/testing/selftests/vm $ make
gcc -Wall -I ../../../../usr/include compaction_test.c -lrt -o /compaction_test
/usr/lib/gcc/x86_64-pc-linux-gnu/4.9.4/../../../../x86_64-pc-linux-gnu/bin/ld: cannot open output file /compaction_test: Permission denied
collect2: error: ld returned 1 exit status
make: *** [../lib.mk:54: /compaction_test] Error 1
Since commit a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT")
selftests/vm build fails if run from the "selftests/vm" directory, but
it works in the selftests/ directory. It's quicker to be able to do a
local vm-only build after a tree wipe and this patch allows for it
again.
