driver core: attribute_container: Remove unused functions

2024-09-13T13:41:42Z

I can't find any use of 'attribute_container_add_class_device_adapter' or 'attribute_container_trigger' in git history. Their export decls went in 2006: commit 1740757e8f94 ("[PATCH] Driver Core: remove unused exports") and their docs disappeared in 2016: commit 47cb398dd75a ("Docs: sphinxify device-drivers.tmpl") Remove them.

scsi: drivers: base: Support atomic version of attribute_container_device_trigger

2020-01-16T03:55:36Z

attribute_container_device_trigger invokes callbacks that may fail for one or more classdevs, for instance, the transport_add_class_device callback, called during transport creation, does memory allocation. This information, though, is not propagated to upper layers, and any driver using the attribute_container_device_trigger API will not know whether any, some, or all callbacks succeeded. This patch implements a safe version of this dispatcher, to either succeed all the callbacks or revert to the original state.

device.h: audit and cleanup users in main include dir

2012-03-16T14:38:24Z

The header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker

driver model: constify attribute groups

2009-09-15T16:50:47Z

Let attribute group vectors be declared "const". We'd like to let most attribute metadata live in read-only sections... this is a start. Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

[SCSI] transport_class: BUG if we can't release the attribute container

2008-04-07T17:19:10Z

Every current transport class calls transport_container_release but ignores the return value. This is catastrophic if it returns an error because the containers are part of a global list and the next action of almost every transport class is to free the memory used by the container. Fix this by making transport_container_release a void, but making it BUG if attribute_container_release returns an error ... this catches the root cause of a system panic much earlier. If we don't do this, we get an eventual BUG when the attribute container list notices the corruption caused by the freed memory it's still referencing. Also made attribute_container_release __must_check as a reminder. Cc: Greg KH Signed-off-by: James Bottomley

[SCSI] attribute_container: update to use the group interface

2008-01-23T17:29:17Z

This patch is the beginning of moving the attribute_containers to use attribute groups exclusively. The attr element is now deprecated and will eventually be removed (along with all the hand rolled code for doing exactly what attribute groups do) when all the consumers are converted to attribute groups.

[SCSI] correct attribute_container list usage

2005-08-31T03:44:20Z

One of the changes in the attribute_container code in the scsi-misc tree was to add a lock to protect the list of devices per container. This, unfortunately, leads to potential scheduling while atomic problems if there's a sleep in the function called by a trigger. The correct solution is to use the kernel klist infrastructure instead which allows lockless traversal of a list. Signed-off-by: James Bottomley
