Subject: (decode_header): Use sparse_fixup_header to correct
X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=3ff03c0c5ecd2eb9b5ce22bf17a178fbba11f974;p=chaz%2Ftar

(decode_header): Use sparse_fixup_header to correct
the st_size value.
(print_header): Do not rely on GNUTYPE_SPARSE type.
Use st->stat.st_size to print real file size.
(skip_member): Assign stat_info.file_name to save_name. This fixes
bug reported by Mads Martin Joergensen <mmj@suse.de>
Use sparse_skip_file() to skip sparse members.
