Subject: NFS: Remove the "NFS_CAP_CHANGE_ATTR" capability
X-Git-Tag: omap-for-v4.3/fixes-merge-window~179^2~8
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cd812599796f500b042f5464b6665755eca21137;p=pandora-kernel.git

NFS: Remove the "NFS_CAP_CHANGE_ATTR" capability

Setting the change attribute has been mandatory for all NFS versions, since
commit 3a1556e8662c ("NFSv2/v3: Simulate the change attribute"). We should
therefore not have anything be conditional on it being set/unset.
