Subject: isofs: fix reported st_blocks stat(2) field
X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/doc/datamaps.china.min.js?a=commitdiff_plain;h=8d0759b089e4b67dfcc7cc954724c4da7bb25a87;p=minix.git

isofs: fix reported st_blocks stat(2) field

The st_blocks field should count 512-byte units, not file system
block units.  The previous computation would cause utilities such
as du(1), when used on isofs, to be off by a factor four.
