X-Git-Tag: v2.6.35-rc6~34^2~6
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a78f9f4668949a6588b8872f162e86685c63d023;p=pandora-kernel.git

ocfs2: make xattr extension work with new local alloc reservation.

The old ocfs2_xattr_extent_allocation is too optimistic about
the clusters we can get. So actually if the file system is
too fragmented, ocfs2_add_clusters_in_btree will return us
with EGAIN and we need to allocate clusters once again.

So this patch change it to a while loop so that we can allocate
clusters until we reach clusters_to_add.
