could we use kmalloc instead of kzmalloc in exfat_fill_super() function?

@zhuchuanchun how big is your filesystem? How many RAM do you have? It seems that mounting requires 64 kb of contigious memory (order 4), but your OS has not - only switching to vmalloc will really help you.

The master branch is now rebased to a different base, and all existing previous issues need to be re-evaluated.

https://github.com/arter97/exfat-linux/releases/tag/5.8-1arter97

Please re-open this if you believe the new base is still susceptible to this issue.
