[PATCH v4 0/4] read-cache: call verify_hdr() in a background thread

From: Jeff Hostetler <jeffhost@microsoft.com>

Version 4 of this patch series incorporates the cleanup made by Junio to my 3rd veresion, updates fsck to always verify the checksum, and a new simplified perf test using p0002 as discussed on the mailing list.

================ 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.

Jeff Hostetler (4):
  read-cache: core.checksumindex
  fsck: force core.checksumindex=1
  t1450-fsck: test core.checksumindex
  p0002-read-cache: test core.checksumindex
