2008-03-31[GFS2] Speed up gfs2_write_alloc_required, deprecate gfs2_extent_mapSteven Whitehouse1-17/+19
This patch removes the call to gfs2_extent_map from gfs2_write_alloc_required, instead we call gfs2_block_map directly. This results in fewer overall calls to gfs2_block_map in the multi-block case. Also, gfs2_extent_map is marked as deprecated so that people know that its going away as soon as all the callers have been converted. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

These messages are a regression compared with 2.6.24, which did not flood the syslog with them. The actual underlying problem was introduced in 2.6.23, when somebody made the string parsing no longer accept nul-terminated strings as a valid input to store_uevent(). Eg. "add\0" was valid prior to 2.6.23, where the code regressed to require "add" without the '\0'. This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code once again tolerate the trailing '\0', if present. According to GregKH, this mainly affects older Ubuntu systems, such as the one I have here that requires this fix.

2008-03-30evdev: Release eventual input device grabs when getting disconnectedBjörn Steinbrink1-0/+3
When getting disconnected we need to release eventual grabs on the underlying input device as we also release the input device itself. Otherwise, we would try to release the grab when the client that requested it closes its handle, accessing the input device which might already be freed.

This patch fixes bits of the DRM so to make the radeon DRI work on non-cache coherent PCI DMA variants of the PowerPC processors. It moves the few places that needs change to wrappers to that other architectures with similar issues can easily add their own changes to those wrappers, at least until we have more useful generic kernel API.

This reverts commit b140b99c413ce410197cfcd4014e757cd745226a. [ conflict in drivers/ide/ide-probe.c fixed manually ] It turned out that probing order change causes problems for some drives: http://bugzilla.kernel.org/show_bug.cgi?id=10239 Since root causes are still being investigated and are unlikely to be fixed before 2.6.25 lets revert this change for now. As a result cable detection becomes less reliable when compared with 2.6.24 but the affected drives are useable again.

2008-03-28driver core: fix small mem leak in driver_add_kobj()Jesper Juhl1-1/+4
The Coverity checker spotted that we leak the storage allocated to 'name' in int driver_add_kobj(). The leak looks legit to me - this is the code : int driver_add_kobj(struct device_driver *drv, struct kobject *kobj, const char *fmt, ...) { va_list args; char *name; int ret; va_start(args, fmt); name = kvasprintf(GFP_KERNEL, fmt, args); ^^^^^^^^ This dynamically allocates space... va_end(args); if (!name) return -ENOMEM; return kobject_add(kobj, &drv->p->kobj, "%s", name); ^^^^^^^^ This neglects to free the space allocated } Inside kobject_add() a copy of 'name' will be made and used. As far as I can see, Coverity is correct in flagging this as a leak, but I'd like some configmation before the patch is applied. This should fix it.

2008-03-28dm crypt: fix ctx pendingMilan Broz1-28/+30
Fix regression in dm-crypt introduced in commit 3a7f6c990ad04e6f576a159876c602d14d6f7fef ("dm crypt: use async crypto"). If write requests need to be split into pieces, the code must not process them in parallel because the crypto context cannot be shared. So there can be parallel crypto operations on one part of the write, but only one write bio can be processed at a time. This is not optimal and the workqueue code needs to be optimized for parallel processing, but for now it solves the problem without affecting the performance of synchronous crypto operation (most of current dm-crypt users). http://bugzilla.kernel.org/show_bug.cgi?id=10242 http://bugzilla.kernel.org/show_bug.cgi?id=10207 Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com> Cc: "Rafael J.

2008-03-28pci: revert SMBus unhide on HP Compaq nx6110Jean Delvare1-5/+6
This reverts commit 3c0a654e390d00fef9d8faed758f5e1e8078adb5 and fixes kernel bug #10245: http://bugzilla.kernel.org/show_bug.cgi?id=10245 The HP Compaq nc6120 has the same PCI sub-device ID as the nx6110, and the SMBus is used by ACPI for thermal management on the nc6120, so Linux should not attach a native driver to it. This means that this quirk is unsafe and has to be removed. I also added a comment to help developers realize that adding new IDs to this SMBus unhiding quirk table should be done only with great care, and in particular only after checking that ACPI is not making use of the SMBus.
