block: don't return -EINVAL for not found names in devt_from_devname

2023-06-22T15:09:33Z

When we didn't find a device and didn't guess it might be a partition, it might still show up later, so don't disable rootwait for it by returning -EINVAL.

block: Improve kernel-doc headers

2023-06-21T19:18:15Z

Fix the documentation of the devt_from_partuuid() return value. Fix the following two recently introduced kernel-doc warnings: block/bdev.c:570: warning: Function parameter or member 'hops' not described in 'bd_finish_claiming' block/early-lookup.c:46: warning: Function parameter or member 'devt' not described in 'devt_from_partuuid' Cc: Christoph Hellwig Fixes: 0718afd47f70 ("block: introduce holder ops") Fixes: cf056a431215 ("init: improve the name_to_dev_t interface") Signed-off-by: Bart Van Assche Link: https://lore.kernel.org/r/20230621165054.743815-1-bvanassche@acm.org Signed-off-by: Jens Axboe

block: fix rootwait= again

2023-06-09T17:38:10Z

The previous rootwait fix added an -EINVAL return to a completely bogus superflous branch, fix this.

block: fix rootwait=

2023-06-07T14:00:14Z

Failures to look up the gendisk must return -ENODEV so that rootwait retries the lookup instead of -EINVAL which exits early.

block: mark early_lookup_bdev as __init

2023-06-05T17:10:14Z

early_lookup_bdev is now only used during the early boot code as it should, so mark it __init to not waste run time memory on it. Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20230531125535.676098-25-hch@lst.de Signed-off-by: Jens Axboe

block: move more code to early-lookup.c

2023-06-05T16:57:40Z

blk_lookup_devt is only used by code in early-lookup.c, so move it there. printk_all_partitions and it's helper bdevt_str are only used by the early init code in init/do_mounts.c, so they should go there as well.

block: move the code to do early boot lookup of block devices to block/

2023-06-05T16:57:40Z

Create a new block/early-lookup.c to keep the early block device lookup code instead of having this code sit with the early mount code. Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20230531125535.676098-16-hch@lst.de Signed-off-by: Jens Axboe
