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