Subject: pNFS: Clear NFS_LAYOUT_RETURN_REQUESTED when invalidating the layout stateid
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ae5a459d5f65c3e83f3e14068dde5fb9c9d81807;p=linux-beck.git

pNFS: Clear NFS_LAYOUT_RETURN_REQUESTED when invalidating the layout stateid

We must ensure that we don't schedule a layoutreturn if the layout stateid
has been marked as invalid.

Fixes: 2a59a0411671e ("pNFS: Fix pnfs_set_layout_stateid() to clear...")
