Zhansaya Bagdauletkyzy a40c80e348 selftests: vm: add KSM unmerge test ... Add check_ksm_unmerge() function to verify that KSM is properly unmerging shared pages. For this, two duplicate pages are merged first and then their contents are modified. Since they are not identical anymore, the pages must be unmerged and the number of merged pages has to be 0. The test is run as follows: ./ksm_tests -U Link: https://lkml.kernel.org/r/c0f55420440d704d5b094275b4365aa1b2ad46b5.1626252248.git.zhansayabagdaulet@gmail.com Signed-off-by: Zhansaya Bagdauletkyzy <zhansayabagdaulet@gmail.com> Reviewed-by: Pavel Tatashin <pasha.tatashin@soleen.com> Reviewed-by: Tyler Hicks <tyhicks@linux.microsoft.com> Cc: Hugh Dickins <hughd@google.com> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2021-09-03 09:58:18 -07:00
