The patch titled
Subject: logfs: clarify MTD dependency
has been removed from the -mm tree. Its filename was
logfs-clarify-mtd-dependency.patch
This patch was dropped because it was folded into logfs-fix-logfs-build-errors-and-dependencies.patch
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: logfs: clarify MTD dependency
After a change to the way that composite modules work, we get
a logfs build error:
fs/built-in.o: In function `logfs_mount':
:(.text+0x139d34): undefined reference to `logfs_get_sb_mtd'
fs/built-in.o: In function `logfs_get_sb_bdev':
:(.text+0x13aa08): undefined reference to `logfs_get_sb_mtd'
This patch avoids the error by changing the dependencies of
logfs in a way that we can no longer configure logfs as built-in
when the MTD core is a loadable module, while leaving the
dependency to require at least one of MTD or BLOCK to be
enabled.
Another patch tried to work around the problem, but accidentally
dropped the dependency on 'BLOCK || MTD', allowing the file
system to be built if neither is selected.
Fixes: cf4f21938e13 ("kbuild: Allow to specify composite modules with modname-m")
Fixes: e6be296f680c ("logfs: fix logfs build errors and dependencies")
