nfsd: don't break lease on CLAIM_DELEGATE_CUR
commit 0c12eaff upstream. CLAIM_DELEGATE_CUR is used in response to a broken lease; allowing it to break the lease and return EAGAIN leaves the client unable to make progress in returning the delegation nfs4_get_vfs_file() now takes struct nfsd4_open for access to the claim type, and calls nfsd_open() with NFSD_MAY_NOT_BREAK_LEASE when claim type is CLAIM_DELEGATE_CUR Signed-off-by: Casey Bodley <cbodley@citi.umich.edu> Signed-off-by: J.
