13 UBIFS is a file system for flash devices which works on top of UBI.
16 bool "Extended attributes support"
19 This option enables support of extended attributes.
21 config UBIFS_FS_ADVANCED_COMPR
22 bool "Advanced compression options"
25 This option allows to explicitly choose which compressions, if any,
26 are enabled in UBIFS. Removing compressors means inability to read
27 existing file systems.
32 bool "LZO compression support" if UBIFS_FS_ADVANCED_COMPR
36 LZO compressor is generally faster than zlib but compresses worse.
40 bool "ZLIB compression support" if UBIFS_FS_ADVANCED_COMPR
44 Zlib compresses better than LZO but it is slower. Say 'Y' if unsure.
46 # Debugging-related stuff
48 bool "Enable debugging"
53 This option enables UBIFS debugging.
55 config UBIFS_FS_DEBUG_MSG_LVL
56 int "Default message level (0 = no extra messages, 3 = lots)"
57 depends on UBIFS_FS_DEBUG
60 This controls the amount of debugging messages produced by UBIFS.
61 If reporting bugs, please try to have available a full dump of the
62 messages at level 1 while the misbehaviour was occurring. Level 2
63 may become necessary if level 1 messages were not enough to find the
64 bug. Generally Level 3 should be avoided.
66 config UBIFS_FS_DEBUG_CHKS
67 bool "Enable extra checks"
68 depends on UBIFS_FS_DEBUG
70 If extra checks are enabled UBIFS will check the consistency of its
71 internal data structures during operation. However, UBIFS performance
72 is dramatically slower when this option is selected especially if the
