Fix build errors that happen when CONFIG_LOGFS=y and CONFIG_MTD=m: fs/built-in.o: In function `logfs_mount': super.c:(.text+0x92a6f): undefined reference to `logfs_get_sb_mtd' fs/built-in.o: In function `logfs_get_sb_bdev': (.text+0x93530): 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.

Flash filesystem aimed to scale efficiently to large devices.
|
|
In comparison to JFFS2 it offers significantly faster mount
|
|
times and potentially less RAM usage, although the latter has
|
|
not been measured yet.
|
|
|
|
In its current state it is still very experimental and should
|
|
not be used for other than testing purposes.

If unsure, say N.
