Abstract
Implementations are provided herein for sub-block ranged locking on a journal block. A file system locking scheme can be adjusted to provide ranged locks on sub-blocks of a journal block. By locking sub-block ranges of a journal block, two independent operations on the same block that do not overlap on a sub-block range can operate independent of each other and be processed concurrently without requiring an exclusive lock over the entire block. Delta write locks, delta read locks, and shared locks can be established on a sub-block range level.
