-# Debugging-related stuff
-config UBIFS_FS_DEBUG
- bool "Enable debugging support"
- depends on UBIFS_FS
- select DEBUG_FS
- select KALLSYMS
- help
- This option enables UBIFS debugging support. It makes sure various
- assertions, self-checks, debugging messages and test modes are compiled
- in (this all is compiled out otherwise). Assertions are light-weight
- and this option also enables them. Self-checks, debugging messages and
- test modes are switched off by default. Thus, it is safe and actually
- recommended to have debugging support enabled, and it should not slow
- down UBIFS. You can then further enable / disable individual debugging
- features using UBIFS module parameters and the corresponding sysfs
- interfaces.
