 Description   

MDEV-16264 failed to convert the thread trx_rollback_all_recovered into tasks.

Ideally, we could roll back multiple recovered incomplete transactions in parallel, by submitting multiple tasks. It could be meaningful to use the same task group as purge, and to prioritize the rollback tasks over purge.

This might complicate the progress reporting (MDEV-12323) and the innodb_fast_shutdown=3 logic (MDEV-15832).
