[LTP] [RFC PATCH] fallocate05: increase the fallocate and defallocate size

[Ralph Siemsen]

Thanks for the suggestions!

I have tried setting .dev_min_size = 64, in addition to setting 
FALLOCATE_BLOCKS back to the previous value of 16. Unfortunately I am 
still seeing OOM when filling the tmpfs. I am confident I made the 
change correctly, as I can see the message:

tst_test.c:903: TINFO: Limiting tmpfs size to 64MB

For other filesystems (ext4/btrfs/vfat) the test is fine, and I get 
ENOSPC error as expected.

I'm testing on kernel version 5.10.52 currently, but I could also switch 
back to 4.19. I'm on ARMv7 rather than amd64.

Regards,
Ralph
