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 support"
52 This option enables UBIFS debugging support. It makes sure various
53 assertions, self-checks, debugging messages and test modes are compiled
54 in (this all is compiled out otherwise). Assertions are light-weight
55 and this option also enables them. Self-checks, debugging messages and
56 test modes are switched off by default. Thus, it is safe and actually
57 recommended to have debugging support enabled, and it should not slow
58 down UBIFS. You can then further enable / disable individual debugging
59 features using UBIFS module parameters and the corresponding sysfs
62 config UBIFS_FS_DEBUG_CHKS
63 bool "Enable extra checks"
64 depends on UBIFS_FS_DEBUG
66 If extra checks are enabled UBIFS will check the consistency of its
67 internal data structures during operation. However, UBIFS performance
68 is dramatically slower when this option is selected especially if the
