Re: [PATCH 5.15 101/135] selftest/vm: verify remap destination address in mremap_test

Hello,

This commit is the second backport of the upstream commit 18d609da ("selftest/vm: verify remap destination address in mremap_test"). It re-introduces function is_remap_region_valid and breaks vm selftest target build with the following diagnostics:

mremap_test.c:126:13: error: redefinition of ‘is_remap_region_valid’

The original backport to 5.15 was done as commit 2688d967. This one (0b4e1609) should be reverted.

The same happend with the upstream commit 9c85a9ba ("selftest/vm: verify mmap addr in mremap_test"). Original backport: a17404fc, repeated backport with just the new function added: e8b99895. Build error message:

mremap_test.c:147:27: error: redefinition of ‘get_mmap_min_addr’

Thank you
