dm vdo: use a proper Makefile for dm-vdo

2024-02-20T18:43:17Z

Requires moving dm-vdo-target.c into drivers/md/dm-vdo/ This change adds a proper drivers/md/dm-vdo/Makefile and eliminates the abnormal use of patsubst in drivers/md/Makefile -- which was the cause of at least one build failure that was reported by the upstream build bot. Also, split out VDO's drivers/md/dm-vdo/Kconfig and include it from drivers/md/Kconfig Signed-off-by: Mike Snitzer Signed-off-by: Matthew Sakai

dm vdo: enable configuration and building of dm-vdo

2024-02-20T18:43:16Z

dm-vdo targets are not supported for 32-bit configurations. A vdo target typically requires 1 to 1.5 GB of memory at any given time, which is likely a large fraction of the addressable memory of a 32-bit system. At the same time, the amount of addressable storage attached to a 32-bit system may not be large enough for deduplication to provide much benefit. Because of these concerns, 32-bit platforms are deemed unlikely to benefit from using a vdo target, so dm-vdo is targeted only at 64-bit platforms.

treewide: replace or remove redundant def_bool in Kconfig files

2024-02-20T11:47:45Z

'def_bool X' is a shorthand for 'bool' plus 'default X'. 'def_bool' is redundant where 'bool' is already present, so 'def_bool X' can be replaced with 'default X', or removed if X is 'n'. Signed-off-by: Masahiro Yamada

fs: add CONFIG_BUFFER_HEAD

2023-08-02T15:13:09Z

Add a new config option that controls building the buffer_head code, and select it from all file systems and stacking drivers that need it. For the block device nodes and alternative iomap based buffered I/O path is provided when buffer_head support is not enabled, and iomap needs a a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call into the buffer_head code when it doesn't exist. Otherwise this is just Kconfig and ifdef changes.
