2007-10-12Driver core: change add_uevent_var to use a structKay Sievers
This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

2007-03-15[PATCH] sysfs and driver core: add callback helper, used by SCSI and S390Alan Stern
This patch (as868) adds a helper routine for device drivers that need to set up a callback to perform some action in a different process's context. This is intended for use by attribute methods that want to unregister themselves or their parent device. Attribute method calls are mutually exclusive with unregistration, so such actions cannot be taken directly. Two attribute methods are converted to use the new helper routine: one for SCSI device deletion and one for System/390 ccwgroup devices.

2006-08-30[S390] cio: kernel stack overflow.Heiko Carstens
Use different kind of assignment to make sure gcc doesn't create code that creates temp variables on the stack, assigns values to it and copies the content of the whole temp variable to the destination. This reduces stack usage of e.g. ccwgroup_driver_register from 976 to 48 bytes instead.

2006-06-29[S390] ccwgroup device unregister.Cornelia Huck
Work around the problem that a device cannot be unregistered from driver_for_each_device() because of klist node refcounting: Get device after device owned by the driver to be unregistered with driver_find_device() and then unregister it. This works because driver_get_device() gets us out of the region of the elevated klist node refcount. driver_find_device() will always get the next device in the list after the found one has been unregistered.

2006-01-06[PATCH] s390: atomic primitivesMartin Schwidefsky
Hugh Dickins <hugh@veritas.com> Fix the broken atomic_cmpxchg primitive. Add atomic_sub_and_test, atomic64_sub_return, atomic64_sub_and_test, atomic64_cmpxchg, atomic64_add_unless and atomic64_inc_not_zero. Replace old style atomic_compare_and_swap by atomic_cmpxchg. Shorten the whole header by defining most primitives with the two inline functions atomic_add_return and atomic_sub_return. In addition this patch contains the s390 related fixes of Hugh's "mm: fill arch atomic64 gaps" patch.

2006-01-04[PATCH] driver kill hotplug word from sn and others fixPaul Jackson
The first of these changes s/hotplug/uevent/ was needed to compile sn2_defconfig (ia64/sn). The other three files changed are blind changes of all remaining bus_type.hotplug references I could find to bus_type.uevent.

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!
