Subject: debugfs.c: the max length of debugfs argument is too short
X-Git-Tag: v1.42.9~123
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=355ffb2ff566229b8bc3f5f7557e91edff5a767a;p=thirdparty%2Fe2fsprogs.git

debugfs.c: the max length of debugfs argument is too short

The max length of debugfs argument is 256 which is too short, the
arguments are two paths, the PATH_MAX is 4096 according to
/usr/include/linux/limits.h, so use BUFSIZ (which is 8192 on Linux
systems), that's also what the ss library uses.
