This reverts commit a069c266ae.
It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.
So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in. It's not all _that_ big, after all, and the inconvenience
isn't worth it.

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 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.
