Subject: (rename): Use stat, not safe_stat.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d33ed582fc804afef36639a9fbcf8a3e242dc7b7;p=pspp

(rename): Use stat, not safe_stat.
(rename): Compare src and dest inode numbers rather than src
inode and dest *dev* when determining whether src and dest refer
to the same file.  From marc@math.cornell.edu (Marc Parmet).
