libata: whitelist all SAMSUNG MZ7KM* solid-state disks

2018-12-03T19:54:39Z

These devices support read zero after trim (RZAT), as they advertise to the OS. However, the OS doesn't believe the SSDs unless they are explicitly whitelisted. Acked-by: Martin K. Petersen Signed-off-by: Juha-Matti Tilli Signed-off-by: Jens Axboe

ata: remove redundant 'default n' from Kconfig

2018-10-10T20:11:16Z

'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ... Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Jens Axboe
