From: Andrew Gabbasov Date: Tue, 27 Feb 2018 11:33:49 +0000 (+0530) Subject: mmc: card: Don't show eMMC RPMB and BOOT areas in /proc/partitions X-Git-Tag: v4.18-rc1~137^2~75 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=207b652cdbec3f7828251ded2c104eea6d036624;p=thirdparty%2Flinux.git mmc: card: Don't show eMMC RPMB and BOOT areas in /proc/partitions Since RPMB area is accessible via special ioctl only and boot areas are unlikely to contain any partitions, exclude them all from listing in /proc/partitions. This will hide them from various user-level software (e.g. fdisk), thus avoiding unnecessary access attempts.
