From a4391c6465d9c978fd4bded12e34bdde3f5458f0 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 5 Jun 2014 15:21:56 -0600 Subject: blk-mq: bump max tag depth to 10K tags For some scsi-mq cases, the tag map can be huge. So increase the max number of tags we support. Additionally, don't fail with EINVAL if a user requests too many tags. Warn that the tag depth has been adjusted down, and store the new value inside the tag_set passed in.
