Description
Lustre has options to dump logs or crash on eviction events, including: LDLM lock eviction, client [re]connect eviction, stale recovery eviction The options obd_lbug_on_eviction and obd_dump_on_eviction controlcrash/log behavior. This patch adds ability to set these options with
a mask for specific subsystems:
- 1: all minus pinger (old behavior)
- 2: client eviction
- 4: LDLM lock eviction
- 8: recovery stale eviction
- 16: pinger eviction (new)
Also adds log dumping and LBUG behavior for pinger evictions, which previously did not produce logs or crashes.
