Eric Biggers 0f7fddb5a9 fsverity: don't drop pagecache at end of FS_IOC_ENABLE_VERITY ... [ Upstream commit a075bacde2 ] The full pagecache drop at the end of FS_IOC_ENABLE_VERITY is causing performance problems and is hindering adoption of fsverity. It was intended to solve a race condition where unverified pages might be left in the pagecache. But actually it doesn't solve it fully. Since the incomplete solution for this race condition has too much performance impact for it to be worth it, let's remove it for now.
