[PATCH] hostfs: fix mismatch between link_file definition and declaration

[PATCH] hostfs: fix mismatch between link_file definition and declaration

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

The function link_file declaration in the header file has the order
of the two arguments (from, to) swapped when compared to the definition
arguments of (to, from).  Fix this by swapping them around to match
the definition.

This error predates the git history, so no idea when this error
was introduced.

commit bf4f804738544a95b8bc8d6a7e2629c3fc0240dd
Author: jdike <jdike>
Date:   Sat Dec 9 22:52:44 2000 +0000

    hostfs now mostly works.  Almost all of the common operations are now
    implemented, the main exceptions being mknod and executing files from
    a hostfs filesystem.

Enough archaeology for today. :-)

Thanks,

[Walter Harms]

Hi,
Colin is obvously right with that.
But my guess is that the error occured because the
pattern (from, to) is brocken here. Also 

Maybe the maintainer can fix that.

just my 2 cents,

This commit is from the old UML cvs tree.
I did a import to git some time ago and pushed it to:
https://git.kernel.org/pub/scm/linux/kernel/git/rw/uml-history.git/

For classic pre-git stuff, check:
https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/
