fs/logfs: remove depends on CONFIG_EXPERIMENTAL The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

tristate "LogFS file system"
logfs: fix logfs build errors and dependencies 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.
