treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

scsi: target: Rename sbc_ops to exec_cmd_ops

2023-04-12T01:55:36+00:00

The next patches allow us to call the block layer's pr_ops from the backends. This will require allowing the backends to hook into the cmd processing for SPC commands, so this renames sbc_ops to a more generic exec_cmd_ops.

scsi: target: Add the DUMMY flag to rd_mcp

2021-04-06T03:26:38+00:00

This commit adds the DUMMY flag to the rd_mcp backend that forces a logical unit to report itself as not connected device of an unknown type. Essentially this allows users to create devices identical to the device for the virtual LUN 0, making it possible to explicitly create a LUN 0 device and configure its WWNs (e.g. vendor or product name).

2020-10-08T03:50:03+00:00

sg_init_table zeroes its first argument, so the allocation of that argument doesn't have to. the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression x,n,flags; @@ x = - kcalloc + kmalloc_array (n,sizeof(*x),flags) ... sg_init_table(x,n) // Link: https://lore.kernel.org/r/1600601186-7420-3-git-send-email-Julia.Lawall@inria.fr Signed-off-by: Julia Lawall Signed-off-by: Martin K.

target: break up free_device callback

2017-07-07T06:11:37+00:00

With this patch free_device is now used to free what is allocated in the alloc_device callback and destroy_device tears down the resources that are setup in the configure_device callback. This patch will be needed in the next patch where tcmu needs to be able to look up the device in the destroy callback.
