Re: [dm-devel] [PATCH] dm-log: fix return value in create_log_context function



Hi Jon,

Thanks for reviewing this patch.

Thanks, "create disk io client" is better. But I changed as
"couldn't create disk io client" for consistency with other
messages.

When dm_io_client_create function fails in create_log_context function,
return value is set to r but it is not used. r should be returned.
In addition, the warning message is properly corrected so that it doesn't
indicate memory allocation.
