[PATCH v3 0/2] read-cache: call verify_hdr() in a background thread

From: Jeff Hostetler <jeffhost@microsoft.com>

Version 3 of this patch series simplifies this effort to just turn on/off the hash verification using a "core.checksumindex" config variable.

I've preserved the original checksum validation code so that we can force it on in fsck if desired.

It eliminates the original threading model completely.
