This option allows to explicitly choose which compressions, if any,

are enabled in UBIFS. Removing compressors means inbility to read

existing file systems.

If unsure, say 'N'.

LZO compressor is generally faster then zlib but compresses worse.

This controls the amount of debugging messages produced by UBIFS.
|

|
|
If reporting bugs, please try to have available a full dump of the
|
||
|
|
messages at level 1 while the misbehaviour was occurring. Level 2
|
||
|
|
may become necessary if level 1 messages were not enough to find the
|
||
|
|
bug. Generally Level 3 should be avoided.

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.
