Re: Revert "dm space maps: don't reset space map allocation cursor when committing"

Because thin-pool is storage over-commitment, one of the following scenarios exists: constantly create and delete file, then the search doesn't hit the end of the metadata device, but ramdisk hits the end (not support discard). So the cursor doesn't reset.

What you're saying doesn't make any sense.  Especially when you
consider this last part of the commit message:
"Fix these issues by leaving the cursor alone, only resetting when the
  search hits the end of the metadata device."
