2005-10-28[PATCH] drivers/base - fix sparse warningsBen Dooks
There are a number of sparse warnings from the latest sparse snapshot being generated from the drivers/base build. The main culprits are due to the initialisation functions not being declared in a header file. Also, the firmware.c file should include <linux/device.h> to get the prototype of firmware_register() and firmware_unregister(). This patch moves the init function declerations from the init.c file to the base.h, and ensures it is included in all the relevant c sources. It also adds <linux/device.h> to the included headers for firmware.c. The patch does not solve all the sparse errors generated, but reduces the count significantly. drivers/base/core.c:161:1: warning: symbol 'devices_subsys' was not declared.

2005-09-07[SCSI] Re-do "final klist fixes"Linus Torvalds
With the previous commit that introduces the klist enhancements, we can now re-do 2b7d6a8cb9718fc1d9e826201b64909c44a915f4 again.
2005-09-07[SCSI] Revert "final klist fixes"Linus Torvalds
Revert commit 2b7d6a8cb9718fc1d9e826201b64909c44a915f4. The "fix" was known to not even compile. Duh. That's not a fix. That's just stupid. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-08-30[SCSI] attribute container final klist fixesJames Bottomley
Since the attribute container deletes from a klist while it's walking it, it is vulnerable to the problem (and fix) here: http://marc.theaimsgroup.com/?l=linux-scsi&m=112485448830217 The attached fixes this (but won't compile without the above). It also fixes the logical reversal in the traversal loop which meant that we were never actually traversing the loop to hit this bug in the first place.

2005-08-30[SCSI] correct attribute_container list usageJames Bottomley
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 <James.Bottomley@SteelEye.com>
2005-08-28[SCSI] fix transport class corner case after reworkJames Bottomley
If your transport class sets the ATTRIBUTE_CONTAINER_NO_CLASSDEVS flag, then its configure method never gets called. This patch fixes that so that the configure method is called with a NULL classdev. Also remove a spurious inverted comma in the transport_class comments. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-14[SCSI] correct transport class abstraction to work outside SCSIJames Bottomley
I recently tried to construct a totally generic transport class and found there were certain features missing from the current abstract transport class. Most notable is that you have to hang the data on the class_device but most of the API is framed in terms of the generic device, not the class_device. These changes are two fold - Provide the class_device to all of the setup and configure APIs - Provide and extra API to take the device and the attribute class and return the corresponding class_device Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
