Fix format string warnings when printing blksize_t values that vary
across architectures. The warning occurs because blksize_t is defined
differently between architectures: aarch64 architectures blksize_t is
int, on x86-64 it's long-int. Cast the values to long. Fixes warnings
as below.
seek_sanity_test.c:110:45: warning: format '%ld' expects argument of type
'long int', but argument 3 has type 'blksize_t' {aka 'int'}
attr_replace_test.c:70:22: warning: format '%ld' expects argument of type
'long int', but argument 3 has type '__blksize_t' {aka 'int'}
Why not just use %zu instead?
Thanks,
Qu
