Re: [LTP] [PATCH]Fix building error.

Hi, What do you think about it? Any comments are welcome. ^_^ This test is not designed for older kernels like RHEL5.5. Even if fixed the compilation error, the test will not be working correctly due to old KSM interfaces and implementation there. CAI Qian

Re: [LTP] [PATCH]Fix building error.

is unsupported! Anyway, it would be more code to test here and there rather than kernel version. Isn't LTP's guideline to only support the latest and greatest kernels? CAI Qian -- Lotusphere 2011 Register now for Lotusphere 2011

Re: [LTP] [PATCH] munmap() don't check sysctl_max_mapcount

the check() to void. OK, I did not look the code carefully. No it just creates unique directory and changes CWD to it. OK, I will remove it if no one think it would be useful although I think the standard template should correct this in the first place. CAI Qian

Re: [LTP] [PATCH v2] mbind_range() vma merge

What about using /proc/self/maps here and get rid of sprintf() and buf here. OK. Empty line here please. It was removed explicitly to make the code compact. Could you explain the benefit? Thanks. CAI Qian -- What

Re: [LTP] [PATCH] mbind_range() vma merge

You should also create corresponding runtest file entires, otherwise the tests won't get executed by default. The syntax is simple name command to execute. See runtest/* files. Yes, I have fixed that in my local version already. Thanks. CAI Qian

Re: [LTP] [PATCH] mbind_range() vma merge

for places where they are really needed. OK. + if (addr == MAP_FAILED) + tst_brkm(TBROK|TERRNO, NULL, mmap), exit(1); You should use tst_brkm(TBROK|TERRNO, tst_exit, mmap) here. As tst_brkm() exits when pointer to cleanup is not NULL. Yes, just figured that out. CAI

Re: [LTP] [PATCH] Out Of Memory when changing cpuset's mems on NUMA

confusing. I would merge the path_exist and path_vcreate functions into one so that you could declare pathbuf as local variable. OK. Thanks. CAI Qian -- Increase Visibility of Your 3D Game App Earn a Chance To Win $500
