bcache: remove EXPERIMENTAL for Kconfig option 'Asynchronous device registration'

2022-08-02T23:22:41Z

The "Asynchronous device registration (EXPERIMENTAL)" Kconfig option is for 2+ years, it is used when registration takes too much time for massive amount of cached data, to avoid udev task timeout during boot time. Many users and products enable this Kconfig option for quite long time (e.g. SUSE Linux) and it works as expected and no issue reported. It is time to remove the "EXPERIMENTAL" tag from this Kconfig item. Signed-off-by: Coly Li Link: https://lore.kernel.org/r/20220719042724.8498-2-colyli@suse.de Signed-off-by: Jens Axboe

block: make the block holder code optional

2021-08-09T17:50:42Z

Move the block holder code into a separate file as it is not in any way related to the other block_dev.c code, and add a new selectable config option for it so that we don't have to build it without any remapped drivers selected. The Kconfig symbol contains a _DEPRECATED suffix to match the comments added in commit 49731baa41df ("block: restore multiple bd_link_disk_holder() support").

bcache: configure the asynchronous registertion to be experimental

2020-05-27T11:19:36Z

In order to avoid the experimental async registration interface to be treated as new kernel ABI for common users, this patch makes it as an experimental kernel configure BCACHE_ASYNC_REGISTRAION. This interface is for extreme large cached data situation, to make sure the bcache device can always created without the udev timeout issue. For normal users the async or sync registration does not make difference. In future when we decide to use the asynchronous registration as default behavior, this experimental interface may be removed. Signed-off-by: Coly Li Signed-off-by: Jens Axboe

bcache: use routines from lib/crc64.c for CRC64 calculation

2018-08-22T17:52:48Z

Now we have crc64 calculation in lib/crc64.c, it is unnecessary for bcache to use its own version. This patch changes bcache code to use crc64 routines in lib/crc64.c.
