ata: libata-eh: Simplify reset operation management

2025-07-16T07:31:43+00:00

Introduce struct ata_reset_operations to aggregate in a single structure the definitions of the 4 reset methods (prereset, softreset, hardreset and postreset) for a port. This new structure is used in struct ata_port to define the reset methods for a regular port (reset field) and for a port-multiplier port (pmp_reset field). A pointer to either of these fields replaces the 4 reset method arguments passed to ata_eh_recover() and ata_eh_reset(). The definition of the reset methods for all drivers is changed to use the reset and pmp_reset fields in struct ata_port_operations. A large number of files is modifed, but no functional changes are introduced. Suggested-by: Niklas Cassel Signed-off-by: Damien Le Moal Reviewed-by: Niklas Cassel Reviewed-by: Martin K.

block: simplify tag allocation policy selection

2025-01-06T14:37:41+00:00

Use a plain BLK_MQ_F_* flag to select the round robin tag selection instead of overlaying an enum with just two possible values into the flags space. Doing so allows adding a BLK_MQ_F_MAX sentinel for simplified overflow checking in the messy debugfs helpers.

ata: fix debounce timings type

2023-08-02T08:37:06+00:00

sata_deb_timing_{hotplug|long|normal}[] store 'unsigned long' debounce timeouts in ms, while sata_link_debounce() eventually uses those timeouts by calling ata_{deadline|msleep}( which take just 'unsigned int'. Change the debounce timeout table element's type to 'unsigned int' -- all these timeouts happily fit into 'unsigned int'... Signed-off-by: Sergey Shtylyov Signed-off-by: Damien Le Moal
