min_free_kbytes incorrect results
Hi all,
I've been running 'min_free_kbytes' from 'runtest/mm', but everytime I'm getting an incorrect value on read. I've tried this test on different machines (different architectures) and with different versions of ltp, but I'm getting the same error on read. I've looked at the test, but the code seems fine. If anybody has any ideea why this isn't working please let me know.
The following log was generated using an up-to-date Arch Linux x64 using
kernel: 3.17.4-1
-------------------------------------------------------------------------------------------------
min_free_kbytes 0 TINFO : set overcommit_memory to 2 min_free_kbytes 0 TINFO : set min_free_kbytes to 67584 min_free_kbytes 1 TBROK : min_free_kbytes = 6, but expect 67584 min_free_kbytes 2 TBROK : Remaining cases broken min_free_kbytes 0 TINFO : set min_free_kbytes to 67584 min_free_kbytes 0 TINFO : set overcommit_memory to 0
incrementing stop

Please let me know if I can be of any assistance.
Kind regards,
Catalin

This failure comes from function set_sys_tune() from testcases/kernel/mem/lib/mem.c
What the code does is to write to the specified file in /sys and then reads it back to verify its content. And it looks like the number read back is truncated so something seems to be broken.
