[PATCH 0/2] mmc: update life time and rel write on sysfs read

From: Marc Mattmueller
Date: Wed Mar 09 2022 - 05:40:59 EST


This patchset adds the update of the ext_csd structure when
reading the estimated life time, pre-eol info or reliable
write setting from sysfs. Based on
https://www.spinics.net/lists/linux-mmc/msg56424.html

The reason for this patchset resides in devices running 24/7.
The mmc estimated life time values, pre-eol info and reliable
write setting values were only read at start-up and were not
updated on sysfs read. Thus, these patches add the rel_param,
rel_write_set to sysfs and perform an update of the EXT_CSD
structure when reading form sysfs one of the values
device_life_time_est_typ_a, device_life_time_est_typ_b,
pre_eol_info or rel_write_set.
