drbd: remove drbd_req_make_private_bio

2021-01-27T16:51:48+00:00

Open code drbd_req_make_private_bio in the two callers to prepare
for further changes.  Also don't bother to initialize bi_next as the
bio code already does that that.

block: switch partition lookup to use struct block_device

2020-12-01T21:53:40+00:00

Use struct block_device to lookup partitions on a disk.  This removes
all usage of struct hd_struct from the I/O path.

block: allocate struct hd_struct as part of struct bdev_inode

2020-12-01T21:53:40+00:00

Allocate hd_struct together with struct block_device to pre-load
the lifetime rule changes in preparation of merging the two structures.

Note that part0 was previously embedded into struct gendisk, but is
a separate allocation now, and already points to the block_device instead
of the hd_struct.  The lifetime of struct gendisk is still controlled by
the struct device embedded in the part0 hd_struct.

drbd: remove ->this_bdev

2020-10-05T16:38:33+00:00

DRBD keeps a block device open just to get and set the capacity from
it.  Switch to primarily using the disk capacity as intended by the
block layer, and sync it to the bdev using revalidate_disk_size.

drbd: don't detour through bd_contains for the gendisk

bd_disk is set on all block devices, including those for partitions.

block: rename generic_make_request to submit_bio_noacct

2020-07-01T13:27:24+00:00

generic_make_request has always been very confusingly misnamed, so rename
it to submit_bio_noacct to make it clear that it is submit_bio minus
accounting and a few checks.

tcp: add tcp_sock_set_cork

2020-05-28T18:11:45+00:00

Add a helper to directly set the TCP_CORK sockopt from kernel space
without going through a fake uaccess.  Cleanup the callers to avoid
pointless wrappers now that this is a simple function call.

block: move the part_stat* helpers from genhd.h to a new header

2020-03-25T15:50:09+00:00

These macros are just used by a few files.  Move them out of genhd.h,
which is included everywhere into a new standalone header.

drbd: fifo_alloc() should use struct_size

2020-01-30T04:03:33+00:00

Switching to struct_size for the allocation in fifo_alloc avoids
hard-coding the type of fifo_buffer.values in fifo_alloc. It also
provides overflow protection; to avoid pessimistic code being
generated by the compiler as a result, this patch also switches
fifo_size to unsigned, propagating the change as appropriate.
