Subject: libext2fs: use F_GETFL, not F_GETFD, in unixfd_open
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff659478ec0eb25951ee23641ae7f359e1a132f5;p=thirdparty%2Fe2fsprogs.git

libext2fs: use F_GETFL, not F_GETFD, in unixfd_open

F_GETFD is the fcntl command that returns FD_* flags, but the callsite
wants to look at the O_* flags.  F_GETFL is the fcntl command that
returns the O_* flags, so change the subcommand to be correct.
