Subject: [PATCH] NFS: fix clp->cl_revoked list deletion causing softlock in
|
|
nfsd
|
|
|
|
commit 2d4a532d385f ("nfsd: ensure that clp->cl_revoked list is
|
|
protected by clp->cl_lock") removed the use of the reaplist to
|
|
clean out clp->cl_revoked. It failed to change list_entry() to
|
|
walk clp->cl_revoked.next instead of reaplist.next
|
|
|
|
Fixes: 2d4a532d385f ("nfsd: ensure that clp->cl_revoked list is protected by clp->cl_lock")
