Description
I built the mmap tests from https://github.com/google/gvisor/blob/master/test/syscalls/linux/mmap.cc
Two tests are failing when run on /var/shared_memory. Reproduce on x86_64 with the provided binary and:
export TEST_TMPDIR=/var/shared_memory/ ./mmap_test --gtest_filter=MMapFileTest*SharedTruncatePartialPage
note: the binary needs devel:libgtest devel:libgmock devel:libabsl_strings

I tried a fix, but it could be completely wrong: https://review.haiku-os.org/c/haiku/+/9060
