Debugging infrastructure for async objs: this lets us easily create fast_lists for various object types so they'll be visible in debugfs. Add new object types to the BCH_ASYNC_OBJS_TYPES() enum, and drop a pretty-printer wrapper in async_objs.c. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

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_POSIX_ACL bool "bcachefs POSIX ACL support" depends on BCACHEFS_FS select FS_POSIX_ACL
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" depends on BCACHEFS_FS help 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" depends on BCACHEFS_FS depends on SMP default y help Instead of immediately sleeping when attempting to take a six lock that is held by another thread, spin for a short while, as long as the thread owning the lock is running.
config BCACHEFS_PATH_TRACEPOINTS bool "Extra btree_path tracepoints" 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.
