block: don't add partitions if GD_SUPPRESS_PART_SCAN is set

2022-09-03T17:29:03Z

Commit b9684a71fca7 ("block, loop: support partitions without scanning") adds GD_SUPPRESS_PART_SCAN for replacing part function of GENHD_FL_NO_PART. But looks blk_add_partitions() is missed, since loop doesn't want to add partitions if GENHD_FL_NO_PART was set. And it causes regression on libblockdev (as called from udisks) which operates with the LO_FLAGS_PARTSCAN. Fixes the issue by not adding partitions if GD_SUPPRESS_PART_SCAN is set.

block: Convert read_part_sector() to use a folio

2022-08-02T16:34:03Z

This relatively straightforward converion saves a call to compound_head() hidden inside put_page(). Signed-off-by: Matthew Wilcox (Oracle)

block: Use PAGE_SECTORS_SHIFT

2022-08-02T16:34:03Z

The bare use of '9' confuses some people. We also don't need this cast, since the compiler does exactly that cast for us. Signed-off-by: Matthew Wilcox (Oracle)

block: Handle partition read errors more consistently

2022-08-02T16:34:03Z

Set p->v to NULL if we try to read beyond the end of the disk, just like we do if we get an error returned from trying to read the disk. Signed-off-by: Matthew Wilcox (Oracle)

block: Simplify read_part_sector()

2022-08-02T16:34:03Z

That rather complicated expression is just trying to find the offset of this sector within a page, and there are easier ways to express that. Signed-off-by: Matthew Wilcox (Oracle)

block: pass a gendisk to blk_queue_set_zoned

Prepare for storing the zone related field in struct gendisk instead of struct request_queue.

2022-06-29T12:51:06Z

If read_mapping_page() sees a page with PageError set, it returns a PTR_ERR(). Checking PageError again is simply dead code. Signed-off-by: Matthew Wilcox (Oracle)
