Structs

CopyStats

Statistics collected during a copy operation

FsyncLatencyTracker

Tracks fsync latency with exponential moving average for adaptive timeout calculation

SmartCopier

Functions

apply_lock

Apply or release a flock on a file, tracking the lock handle by inode in lock_map

btrfs_resolve_inode
