I have increased the timeout to 10 minutes but it did not help.
Same error found.
[ 608.679353] mmc1: Card stuck being busy! mmc_poll_for_busy
[ 608.684964] mmc1: cache flush error -110

OTOH, What best i could do for my own experiment to revert all three patches and
now the reported error gone and device mount successfully .
List of patches reverted,
mmc: core: Specify timeouts for BKOPS and CACHE_FLUSH for eMMC
mmc: block: Use generic_cmd6_time when modifying
mmc: core: Default to generic_cmd6_time as timeout in __mmc_switch()
