Hugepage feature error in SamSung Galaxy S20 Ultra 5G

[John-Yi]

our app will crash at branch Master src/tbbmalloc/tbbmalloc_internal.h line 457:

if (thpPresent == 'y') {
    MALLOC_ASSERT(hugePageSize != 0, "Huge Page size can't be zero if we found thp existence.");
    thpAvailable = true;
}

I use adb shell to check this phone, the file /sys/kernel/mm/transparent_hugepage/ is exist. But cat the /proc/meminfo, can't find out key word:Hugepagesize, only got a similar word: HugepagePool

Is it possible some phone use another word instead of TBB's key word:Hugepagesize?

tbbmalloc relies on Hugepagesize variable availability because it seems to be common on Linux systems (I think it is applicable for Android too). I guess Samsung modified Android kernel for its phones somehow because I didn't find any references to HugepagePool variable except of kernel codes for Samsung phone on GitHub.
@alexey-katranov please correct me if I am wrong somewhere

To tell the truth, I do not know how Hugepagesize is common. However, the crash is not expected if Hugepagesize is not present. I believe it should be deny of service (i.e. do not use huge pages) if the key word is not available.

thx for reply. @isaevil @alexey-katranov Will you release an official version to fix this error?
