X-Git-Tag: 2.7.57~34
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=31234e608fa156761b2d8c48ff60cba875dd4832;p=fs%2Flustre-release.git

LU-6660 rename: DNE2 should return -EXDEV upon remote rename

DNE2 MDS should return -EXDEV upon remote rename, so that old
client can do rename with copy and delete, instead of fail
with -EREMOTE.
