When a tablet is migrated away, any inactive read which might be reading from said tablet, has to be dropped. Otherwise these inactive reads can prevent sstables from being removed and these sstables can potentially survive until the tablet is migrated back and resurrect data. This series introduces the fix as well as a reproducer test. Fixes: https://github.com/scylladb/scylladb/issues/18110 Closes scylladb/scylladb#18179 * github.com:scylladb/scylladb: test: add test for cleaning up cached querier on tablet migration querier: allow injecting cache entry ttl by error injector replica/table: cleanup_tablet(): clear inactive reads for the tablet replica/database: introduce clear_inactive_reads_for_tablet() replica/database: introduce foreach_reader_concurrency_semaphore reader_concurrency_semaphore: add range param to evict_inactive_reads_for_table() reader_concurrency_semaphore: allow storing a range with the inactive reader reader_concurrency_semaphore: avoid detach() in inactive_read_handle::abandon()
