From 6e7434abcd07e8beb67fdc4af6207ae0490d5274 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 9 Sep 2023 19:16:53 -0400 Subject: NFSv4/pnfs: Allow layoutget to return EAGAIN for softerr mounts If we're using the 'softerr' mount option, we may want to allow layoutget to return EAGAIN to allow knfsd server threads to return a JUKEBOX/DELAY error to the client instead of busy waiting.
