From a1d82aff5df760d933b6ea3a03805dbc2bd73eb8 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 27 Dec 2016 14:49:02 -0500 Subject: kernfs: make kernfs_open_file->mmapped a bitfield More kernfs_open_file->mutex synchronized flags are planned to be added. Convert ->mmapped to a bitfield in preparation. While at it, make kernfs_fop_mmap() use "true" instead of "1" on ->mmapped.
