From 577a133988c76e4ebf01d050d0d758d207a1baf7 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 16 Nov 2018 17:45:25 +0100 Subject: [PATCH] file-posix: Fix shared locks on reopen commit s->locked_shared_perm is the set of bits locked in the file, which is the inverse of the permissions actually shared. So we need to pass them as they are to raw_apply_lock_bytes() instead of inverting them again.
