[PATCH] selftests: fix the broken individual test for x86

From: Bamvor Jian Zhang

Next message: Prasant Jalan: "[PATCH] drivers: staging: vt6656: fixed coding style errors"
Previous message: Patrick Bellasi: "Re: [RFC][PATCH v2 2/2] cpufreq: schedutil: Avoid decreasing frequency of busy CPUs"
Next in thread: Bamvor Jian Zhang: "[PATCH] selftests: fix the broken individual test for x86"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Andy Lutomirski report that build individual testcase in x86 is broken:

$ make -C tools/testing/selftests/x86 ldt_gdt_32
make: Entering directory '/home/luto/apps/linux/tools/testing/selftests/x86'
Makefile:44: warning: overriding recipe for target 'clean'
../lib.mk:55: warning: ignoring old recipe for target 'clean'
make: *** No rule to make target 'ldt_gdt_32'. Stop.
make: Leaving directory '/home/luto/apps/linux/tools/testing/selftests/x86'

This patch fix this issue by removing the slash after OUTPUT.
And also mention this use case in Documentation/kselftests.txt
