Subject: [PATCH 47/79] namei: move link/cookie pairs into nameidata
Date: Tue,  5 May 2015 06:22:21 +0100
Message-ID: <1430803373-4948-47-git-send-email-viro@ZenIV.linux.org.uk> (raw)
In-Reply-To: <20150505052205.GS889@ZenIV.linux.org.uk>

From: Al Viro <viro@zeniv.linux.org.uk>

Array of MAX_NESTED_LINKS + 1 elements put into nameidata;
what used to be a local array in link_path_walk() occupies
entries 1 .. MAX_NESTED_LINKS in it, link and cookie from
the trailing symlink handling loops - entry 0.

This is _not_ the final arrangement; just an easily verified
incremental step.
