20 select CRYPTO_POLY1305

29 The bcachefs filesystem - a modern, copy on write filesystem, with
30 support for multiple devices, compression, checksumming, etc.
33 bool "bcachefs quota support"
34 depends on BCACHEFS_FS
37 config BCACHEFS_ERASURE_CODING
38 bool "bcachefs erasure coding (RAID5/6) support (EXPERIMENTAL)"
39 depends on BCACHEFS_FS
42 This enables the "erasure_code" filesysystem and inode option, which
43 organizes data into reed-solomon stripes instead of ordinary
46 WARNING: this feature is still undergoing on disk format changes, and
47 should only be enabled for testing purposes.
49 config BCACHEFS_POSIX_ACL
50 bool "bcachefs POSIX ACL support"
51 depends on BCACHEFS_FS
55 bool "bcachefs debugging"
56 depends on BCACHEFS_FS
58 Enables many extra debugging checks and assertions.
60 The resulting code will be significantly slower than normal; you
61 probably shouldn't select this option unless you're a developer.
64 bool "bcachefs unit and performance tests"
65 depends on BCACHEFS_FS
67 Include some unit and performance tests for the core btree code
69 config BCACHEFS_LOCK_TIME_STATS
70 bool "bcachefs lock time statistics"
71 depends on BCACHEFS_FS
73 Expose statistics for how long we held a lock in debugfs
75 config BCACHEFS_NO_LATENCY_ACCT
76 bool "disable latency accounting and time stats"
77 depends on BCACHEFS_FS
79 This disables device latency tracking and time stats, only for performance testing
81 config BCACHEFS_SIX_OPTIMISTIC_SPIN
82 bool "Optimistic spinning for six locks"
83 depends on BCACHEFS_FS
87 Instead of immediately sleeping when attempting to take a six lock that
88 is held by another thread, spin for a short while, as long as the
89 thread owning the lock is running.
91 config BCACHEFS_PATH_TRACEPOINTS
92 bool "Extra btree_path tracepoints"
93 depends on BCACHEFS_FS
95 Enable extra tracepoints for debugging btree_path operations; we don't
96 normally want these enabled because they happen at very high rates.
98 config MEAN_AND_VARIANCE_UNIT_TEST
99 tristate "mean_and_variance unit tests" if !KUNIT_ALL_TESTS
101 depends on BCACHEFS_FS
102 default KUNIT_ALL_TESTS
104 This option enables the kunit tests for mean_and_variance module.
