Patch 2 fixes behaviour under pressure, retrying inserts in non-permanent error case (-EBUSY). Patch 3 auto-adjusts the upper table size limit according to the number of threads (in concurrency test). In fact, the current default is already too small. Patch 4 makes it possible to retry inserts even in supposedly permanent error case (-ENOMEM) to expose rhashtable's remaining problem of -ENOMEM being not as permanent as it is expected to be. Changes since v1: - Introduce insert_retry() which is then used in single-threaded test as well. - Do not retry inserts by default if -ENOMEM was returned. - Rename the retry counter to be a bit more verbose about what it contains. - Add patch 4 as a debugging aid. ==================== Signed-off-by: David S.
