Subject: libfstools: Fix overflow of F2FS_MINSIZE constant
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ff1ded63c51e84e239fb422ac8b9d15251d1221f;p=project%2Ffstools.git

libfstools: Fix overflow of F2FS_MINSIZE constant

I wasn't able to to use f2fs on armvirt/32 platform and I've found out
that it was due to F2FS_MINSIZE constant overflow leading to value of 13
exabytes instead of 100 megabytes.
