CVS commit: src/tests/kernel

["Taylor R Campbell" <riastradh%netbsd.org@localhost>]

Module Name:    src
Committed By:   riastradh
Date:           Sat Apr 19 01:56:50 UTC 2025

Modified Files:
        src/tests/kernel: t_memfd_create.c

Log Message:
t_memfd_create: Cast size_t to off_t, not vice versa.

off_t is always 64-bit; size_t may be 32- or 64-bit depending on the
architecture and ABI, so casting off_t to size_t may truncate.

Should better resolve this build failure (not sure how I missed it,
definitely compile-tested at least this file on two different
architectures, one of which was evbmips64-eb and the other I have
forgotten):

/tmp/build/2025.04.18.20.51.31-sparc64/src/tests/kernel/t_memfd_create.c:129:9: error: comparison of integer expressions of different signedness: '__off_t' {aka 'long int'} and 'size_t' {aka 'long 
unsigned int'} [-Werror=sign-compare]
