Subject: xprtrdma: Ensure MRs are DMA-unmapped when posting LOCAL_INV fails
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b674c4b4a13dc3d37f1b4a449f3b9515f9a30615;p=linux.git

frwr_release_mr does not DMA-unmap, but the recycle worker does.

Fixes: 61da886bf74e ("xprtrdma: Explicitly resetting MRs is ... ")
