From 7260793c13e9ae730867f0f6515d1af84f24308a Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 14 Feb 2022 15:30:13 -0500 Subject: [PATCH] NFSD: Fix nfsd_breaker_owns_lease() return values [ Upstream commit 50719bf3442dd6cd05159e9c98d020b3919ce978 ] These have been incorrect since the function was introduced. A proper kerneldoc comment is added since this function, though static, is part of an external interface.
