Subject: vfs: Fix O_NOFOLLOW behavior for paths with trailing slashes
X-Git-Tag: v2.6.34~22
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=002baeecf53677d2034113e34197ec221f42e037;p=pandora-kernel.git

vfs: Fix O_NOFOLLOW behavior for paths with trailing slashes

According to specification

	mkdir d; ln -s d a; open("a/", O_NOFOLLOW | O_RDONLY)

should return success but currently it returns ELOOP.  This is a
regression caused by path lookup cleanup patch series.

Fix the code to ignore O_NOFOLLOW in case the provided path has trailing
slashes.
