The bcachefs filesystem - a modern, copy on write filesystem, with
support for multiple devices, compression, checksumming, etc.

config BCACHEFS_ERASURE_CODING bool"bcachefs erasure coding (RAID5/6) support (EXPERIMENTAL)"
depends on BCACHEFS_FS
select QUOTACTL
help This enables the "erasure_code" filesysystem and inode option, which
organizes data into reed-solomon stripes instead of ordinary
replication.
WARNING: this feature is still undergoing on disk format changes, and
should only be enabled for testing purposes.
config BCACHEFS_DEBUG bool"bcachefs debugging"
depends on BCACHEFS_FS
help
Enables many extra debugging checks and assertions.
The resulting code will be significantly slower than normal; you
probably shouldn't select this option unless you're a developer.
config BCACHEFS_INJECT_TRANSACTION_RESTARTS bool"Randomly inject transaction restarts"
depends on BCACHEFS_DEBUG
help
Randomly inject transaction restarts in a few core paths - may have a
significant performance penalty
config BCACHEFS_TESTS bool"bcachefs unit and performance tests"
depends on BCACHEFS_FS
help
Include some unit and performance tests for the core btree code
config BCACHEFS_LOCK_TIME_STATS bool"bcachefs lock time statistics"

Expose statistics for how long we held a lock in debugfs
config BCACHEFS_NO_LATENCY_ACCT bool"disable latency accounting and time stats"
depends on BCACHEFS_FS
help This disables device latency tracking and time stats, only for performance testing
config BCACHEFS_SIX_OPTIMISTIC_SPIN bool"Optimistic spinning for six locks"

Instead of immediately sleeping when attempting to take a six lock that
is held by another thread, spin for a shortwhile, as long as the
thread owning the lock is running.

depends on BCACHEFS_FS && TRACING
help
Enable extra tracepoints for debugging btree_path operations; we don't
normally want these enabled because they happen at very high rates.
