Re: [PATCH V2] scsi: fix race on creating sense cache

Ming,

When scsi_init_sense_cache(host) is called concurrently from different hosts, each code path may see that the cache isn't created, then try to create a new one, then the created sense cache may be overrided and leaked.

Fixes the issue by moving 'mutex_lock(&scsi_sense_cache_mutex)' before scsi_select_sense_cache().

Applied to 5.3/scsi-fixes, thanks!
