Remove debug message level and debug checks Kconfig options as they proved to be useless anyway. We have sysfs interface which we can use for fine-grained debugging messages and checks selection, see Documentation/filesystems/ubifs.txt for mode details.

This option allows to explicitly choose which compressions, if any,
|
|
are enabled in UBIFS. Removing compressors means inability to read
|
|
existing file systems.
|

If unsure, say 'N'.

LZO compressor is generally faster than zlib but compresses worse.

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.

help
|
|
If extra checks are enabled UBIFS will check the consistency of its
|
|
internal data structures during operation. However, UBIFS performance
|
|
is dramatically slower when this option is selected especially if the
|
|
file system is large.
