From: Jens Axboe <axboe@suse.de> Although it was an established part of the current bio api, it was never documented that bio_add_page() and merge_bvec_fn() must accept to add at least one page to an empty bio.

From: Adrian Bunk <bunk@fs.tum.de> The 2.6 Kconfig language allows to set the range for integer questions. The patch below adds a range line on all architectures that have a NR_CPUS question except ia64. The help text on ia64 didn't suggest any values. Could someone tell the correct values for ia64 (and if it's only a minimum value of 2)?

From: "Martin J. Bligh" <mbligh@aracnet.com> Patches are a damned sight easier to read if people use the '-p' option to diff ... this generates output that looks like this: "@@ -323,6 +323,7 @@ void put_dirty_page(struct task_struct *" for each block. This patch simply adds that to the documentation file, in the hope of steering new users in the right direction.

From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Larger modules fail to load with the message "Relocation overflow vs section 17", or some other section number. This failure happens with GPRELHIGH relocation, which is *signed* short, but relocation overflow check in module.c doesn't take into account the sign extension.

From: Matthew Dobson <colpatch@us.ibm.com> This patch does the following: 1) Rename ZONE_SHIFT to NODEZONE_SHIFT. This value is the number of bits to shift page->flags to get the node/zone part of the bitfield. 2) Add a macro called NODEZONE which takes a node number and zone number and returns a 'nodezone', a bitshifted composition of the two. 3) Create page_zonenum & page_nodenum, inline functions to return the node/zone a page belongs to with some simple bit twiddling, no pointer dereferences necessary. 4) Modify page_zone() and set_page_zone() to use the new NODEZONE_SHIFT. 5) Modify memmap_init_zone() & free_area_init_core() to use the new NODEZONE macros. 6) Fix up some comments to reflect the above changes.

From: Christophe Saout <christophe@saout.de> The intent of these are to clarify the meaning of the bio fields in the bi_end_io function (since we are already mostly there). After these small modifications bio->bi_idx and the corresponding bio_iovec(bio)->bv_offset point to the beginning of the completed data, together with the nr_bytes argument you know exactly what data was finished, e.g. when you can't track it otherwise (or it would be unnecessary expensive). Apart from that it's a nice-to-have. The first mini-patch moves the update of bio_iovec(bio)->bv_offset and ->bv_len after the call of bi_end_io where bi_idx gets updated so they get updated together. Ok with Jens. The second part of the patch modifies the multwrite hack in PIO non- taskfile ide disk code. It modifies the bi_idx field to walk the bios and doesn't reset it correctly before ending the request. The patch uses the segment counter in the request field to correctly restore the bi_idx field before ending the request. Can't possibly break anything since it's working on the local request copy ("scratchpad") anyway. Also does this in legacy/pdc4030.c (similar code). The code modified here is going to die anyway any trying to fix it would be too invasive. Ok with Bartlomiej.

From: Manfred Spraul <manfred@colorfullife.com> readdir on /proc has two problems: reading all entries is O(N^2), and entries are overlooked if tasks die in the middle of readdir: the readdir implementation remembers the offset into the task list, and if a task (actually: process) that was returned by previous readdir calls exits, then a random entry is dropped. The attached patch fixes the O(N^2) by using f_version to store the pid of the task that should be returned next. This speeds up reading /proc to O(N). Additionally, it mitigates the effects of dying tasks: Tasks are skipped only if the task whose pid is stored in f_version exits, all other task deaths have no effect. Unfortunately the code has a bad worst case behavior: if the targeted task exits and a new task with the same pid is created, then all entries in the task list between old and new position are dropped. This should be rare.

From: Rusty Russell <rusty@rustcorp.com.au> It turns out that run_workqueue never has signal_pending(), since setting the handler to SIG_IGN means "don't make zombies, I'm ignoring them". Fix the comment, don't allow the signal, and remove the unused waitpid loop. This also allows simpler conversion of workueues to the kthread mechanism, which uses signals to indicate it's time to stop.

From: Armin <armin@melware.de> The new driver for Eicon ISDN cards is in drivers/isdn/hardware/eicon. The old driver is still in drivers/isdn/eicon and I would like to remove this old driver from the 2.6 kernels. The attached patch removes the references to this driver, but in addition the directory drivers/isdn/eicon should be removed.
