Fixing it will let more people enable THP by default. but anyway we will disable it now if the issue can't be fixed.Did you try what happens with transparent_hugepage=madvise? If that doesn't fix it, it's min_free_kbytes issue.
with madvise, the min_free_kbytes is still high (same as the 'always' case). The result is still we have about 50M memory is reserved. you can try at your machine with boot option 'mem=2G' and check the zoneinfo output.
