[lustre-devel] [PATCH 26/28] lustre: mdc: set correct body eadatasize for getxattr()

[James Simmons <jsimmons@infradead.org>]

From: "John L. Hammond" <jhammond@whamcloud.com>

In mdc_intent_getxattr_pack() set mbo_eadatasize to the size of the
xattr values buffer rather than the size of the xattr names buffer.
Only the xattr values buffer should be upsized for older MDTs.
