[Concept,06/23] linux: Add namei.h with pathname lookup flags
Commit Message
From: Simon Glass <simon.glass@canonical.com>
Create linux/namei.h with LOOKUP_* flags for pathname resolution
operations used by filesystem code.
Update ext4_uboot.h to use linux/namei.h instead of duplicating
the LOOKUP_FOLLOW definition.
