Running git grep '\$here' tests/qemu-iotests has 0 hits, which means we are setting a variable that has no use. It appears that commit e8f8624d removed the last use. So execute the following cmd to remove all of the 'here=...' lines as dead code. sed -i '/^here=/d' $(git grep -l '^here=' tests/qemu-iotests) Cc: kwolf@redhat.com Cc: mreitz@redhat.com Cc: eblake@redhat.com Suggested-by: Eric Blake <eblake@redhat.com> Signed-off-by: Mao Zhongyi <maozhongyi@cmss.chinamobile.com> Message-Id: <20181024094051.4470-3-maozhongyi@cmss.chinamobile.com> Reviewed-by: Eric Blake <eblake@redhat.com> [eblake: touch up commit message, reorder series, rebase to master] Signed-off-by: Eric Blake <eblake@redhat.com>
