block: store a block_device pointer in struct bio

2021-01-25T01:17:20+00:00

Replace the gendisk pointer in struct bio with a pointer to the newly
improved struct block device.  From that the gendisk can be trivially
accessed with an extra indirection, but it also allows to directly
look up all information related to partition remapping.

bcache: only use block_bytes() on struct cache

2020-10-02T20:25:30+00:00

Because struct cache_set and struct cache both have struct cache_sb,
therefore macro block_bytes() can be used on both of them. When removing
the embedded struct cache_sb from struct cache_set, this macro won't be
used on struct cache_set anymore.

This patch unifies all block_bytes() usage only on struct cache, this is
one of the preparation to remove the embedded struct cache_sb from
struct cache_set.

bcache: add set_uuid in struct cache_set

2020-10-02T20:25:30+00:00

This patch adds a separated set_uuid[16] in struct cache_set, to store
the uuid of the cache set. This is the preparation to remove the
embedded struct cache_sb from struct cache_set.

bcache: Fix an error code in bch_dump_read()

2019-09-03T14:08:29+00:00

The copy_to_user() function returns the number of bytes remaining to be
copied, but the intention here was to return -EFAULT if the copy fails.

bcache: do not check if debug dentry is ERR or NULL explicitly on remove

2018-12-13T15:15:54+00:00

debugfs_remove and debugfs_remove_recursive will check if the dentry
pointer is NULL or ERR, and will do nothing in that case.

Remove the check in cache_set_free and bch_debug_init.

bcache: replace printk() by pr_*() routines

2018-08-11T21:46:41+00:00

There are still many places in bcache use printk to display kernel
message, which are suggested to be preplaced by pr_*() routines like
pr_err(), pr_info(), or pr_notice().

This patch replaces all printk() with a proper pr_*() routine for
bcache code.

bcache: style fixes for lines over 80 characters

2018-08-11T21:46:41+00:00

This patch fixes the lines over 80 characters into more lines, to minimize
warnings by checkpatch.pl. There are still some lines exceed 80 characters,
but it is better to be a single line and I don't change them.
