From: Christoph Hellwig <hch@lst.de> To be useful for distribution kernels it needs to be a runtime option. The original patch is from Joerg Platte via the Debian kernel package, with some adjustments from me (and me too - Bart). Signed-off-by:

Presently we get procfs warnings from ipmi_si.ko due to its failing to remove all of a /proc directory's contents prior to removing that directory. This patch tracks all proc entries for an IPMI interface and unregisters them all upon removal. Signed-off-by:

From: Colin Leroy <colin@colino.net> Paulus brought this up on IRC, it seems to be a bad DRM merge: The code #ifndef VMAP_4_ARGS if ( dev->agp->cant_use_aperture ) return -EINVAL; #endif in DRM(agp_acquire) should be removed altogether in a 2.6 kernel because its vmap() takes 4 arguments; however, only the guards seem to have been removed, which causes this function to erroneously fail if the AGP aperture can't be directly accessed by the CPU.

The attached patch fixes the EDID parsing for PPC on rivafb. It actually finds the EDID info in the OF Tree now. I grabbed this from BenHs Tree as of 2.6.5-rc3. The current code has no chance to work since it doesn't walk the device tree. This helps rivafb on PPC at least a bit further... Signed-off-by:

David Mosberger noticed bw_pipe was way down on sched-domains kernels on SMP systems. That is due to two things: first, the previous wake-affine logic would *always* move a pipe wakee onto the waker's CPU. With the scheduler rework, this was toned down a lot (but extended to all types of wakeups). One of the ways this was damped was with the logic: don't move the wakee if its CPU is relatively idle compared to the waker's CPU. Without this, some workloads would pile everything up onto a few CPUs and get lots of idle time. However, the fix was a bit of a blunt hack: if the wakee runqueue was below 50% busy, and the waker's was above 50% busy, we wouldn't do the move. I think a better way to capture it is what this patch does: if the wakee runqueue is below 100% busy, and the sum of the two runqueue's loads is above 100% busy, and the wakee runqueue is less busy than the waker runqueue (ie. CPU utilisation would drop if we do the move), then we don't do the move. After I fixed this, I found things were still getting bounced around quite a bit. The reason is that we were attempting very aggressive idle balancing in order to cut down idle time in a dbt2-pgsql workload, which is particularly sensitive to idle. After having Mark Wong (markw@osdl.org) retest this load with this patch, it looks like we don't need to be so aggressive. I'm glad to be rid of this because it never sat too well with me. We should see slightly lower cost of schedule and slightly improved cache impact with this change too. Mark said: --- This looks pretty good: metric kernel 2334 2.6.7-rc2 2298 2.6.7-rc2-mm2 2329 2.6.7-rc2-mm2-sched-more-wakeaffine --- ie. within the noise. David said: --- Oooh, me likeee! Host OS Pipe AF UNIX --------- ------------- ---- ---- caldera.h Linux 2.6.6 3424 2057 (plain 2.6.6) caldera.h Linux 2.6.7-r 333. 1402 (original 2.6.7-rc1) caldera.h Linux 2.6.7-r 3086 4301 (2.6.7-rc1 with your patch) Pipe-bandwidth is still down about 10% but that may be due to unrelated changes (or perhaps warmup effects?). The AF UNIX bandwidth is just mindboggling. Moreover, with your patch 2.6.7-rc1 shows better context-switch times and lower communication latencies (more like the numbers you're getting on UP). So it seems like the overall balance of keeping things on the same CPU vs. distributing them across CPUs is improved. --- I also ran some tests on the NUMAQ. kernbench, dbench, hackbench, reaim were much the same. tbench was improved, very much so when clients < NR_CPU.

This condtion on this loop is primarily to avoid the loop if it doesn't appear to be needed. However it optimises a little too much and there is a case where it skips the loop when it is really needed. This patch fixes it. Signed-off-by:

There's a bad length check in cdrom_get_random_writable(), it's off-by-4 since fh->data_len is the length of data _after_ that field (which is offset 4 bytes in the header). Check is pretty bogus anyways, so just kill it. Signed-Off-By:

This allows the number of "raid_disks" in a raid1 to be changed. This requires allocating a new pool of "r1bio" structures which a different number of bios, suspending IO, and swapping the new pool in place of the old. (and a few other related changes). Signed-off-by:

It is possible to have raid1/4/5/6 arrays that do not use all the space on the drive. This can be done explicitly, or can happen info you, one by one, replace all the drives with larger devices. This patch extends the "SET_ARRAY_INFO" ioctl (which previously invalid on active arrays) allow some attributes of the array to be changed and implements changing of the "size" attribute. "size" is the amount of each device that is actually used. If "size" is increased, the new space will immediately be "resynced". Signed-off-by:

If raid1 decides it needs to resync it will do so even if there is only one working device. This is pointless. With this patch we abort resync if there is nowhere to write to. Signed-off-by:

md_check_recovery only locks a device and does stuff when it thinks there is a real likelyhood that something needs doing. So the test at the top must cover all possibilities. But it didn't cover the possibility that the last outstanding request on a failed device had finished and so the device needed to be removed. As a result, a failed drive might not get removed from the personalities perspective on the array, and so it could never be removed from the array as a whole. With this patch, whenever ->nr_pending hits zero on a faulty device, MD_RECOVERY_NEEDED is set so that md_check_recovery will do stuff. Signed-off-by:

md/multipath has two separate pieces of code for choosing a device to use, one when a request is first made and the other when a request is being re-tried after failure. This patch discards multipath_read_balance and uses multipath_map in both situations. Signed-off-by:

rsc_lookup is a bit complicated: it either takes responsibility for the memory pointed to by handle.data and sets handle.data to NULL, or it leaves handle.data unchanged, in which case the caller is responsible for freeing handle.data. I forgot that the possibility of inserting a negative cache entry into the cache meant that this could happen even when rsc_lookup is called with set == 0. Note that the ip_map code has the same bug, not that it seems to matter much, since the memory in question in that case is always just a statically allocated string. From: "J.

The server sunrpc code should take a reference on the relevant module before calling any authentication code. Also, it looks to me like the table of authops needs some locking. Finally, gss_svc_init wasn't checking the status of svc_auth_register, and gss_svc_shutdown wasn't calling svc_auth_unregister. From: "J. Bruce Fields" <bfields@fieldses.org> Signed-off-by:

there's a small typo in nfsd_acceptable. It calls err = permission(parent->d_inode, S_IXOTH, NULL); It really wants to use MAY_EXEC instead of S_IXOTH.
