| | | | | | | | | | | | | | | | | | | | | | | - In cgroup_clone(), if vfs_mkdir() returns successfully, dentry->d_fsdata will be the pointer to the newly created cgroup and won't be NULL. - a cgroup file's dentry->d_fsdata won't be NULL, guaranteed by cgroup_add_file(). - When walking through the subsystems of a cgroup_fs (using for_each_subsys), cgrp->subsys[ss->subsys_id] won't be NULL, guaranteed by cgroup_create().

* quota: don't set grace time when user isn't above softlimitJan Kara2009-01-08
| | | | | | | | | | | | do_set_dqblk() allowed SETDQBLK quotactl to set user's grace time even if user was not above his softlimit.

* ext3: allocate ->s_blockgroup_lock separatelyPekka Enberg2009-01-08
| | | | | | | | | | | | | | | | | | As spotted by kmemtrace, struct ext3_sb_info is 17152 bytes on 64-bit which makes it a very bad fit for SLAB allocators. The culprit of the wasted memory is ->s_blockgroup_lock which can be as big as 16 KB when NR_CPUS >= 32. To fix that, allocate ->s_blockgroup_lock, which fits nicely in a order 2 page in the worst case, separately. This shinks down struct ext3_sb_info enough to fit a 1 KB slab cache so now we allocate 16 KB + 1 KB instead of 32 KB saving 15 KB of memory.

* jbd: improve fsync batchingJosef Bacik2009-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a flaw with the way jbd handles fsync batching. If we fsync() a file and we were not the last person to run fsync() on this fs then we automatically sleep for 1 jiffie in order to wait for new writers to join into the transaction before forcing the commit. The problem with this is that with really fast storage (ie a Clariion) the time it takes to commit a transaction to disk is way faster than 1 jiffie in most cases, so sleeping means waiting longer with nothing to do than if we just committed the transaction and kept going. Ric Wheeler noticed this when using fs_mark with more than 1 thread, the throughput would plummet as he added more threads. This patch attempts to fix this problem by recording the average time in nanoseconds that it takes to commit a transaction to disk, and what time we started the transaction. If we run an fsync() and we have been running for less time than it takes to commit the transaction to disk, we sleep for the delta amount of time and then commit to disk. We acheive sub-jiffie sleeping using schedule_hrtimeout. This means that the wait time is auto-tuned to the speed of the underlying disk, instead of having this static timeout. I weighted the average according to somebody's comments (Andreas Dilger I think) in order to help normalize random outliers where we take way longer or way less time to commit than the average. I also have a min() check in there to make sure we don't sleep longer than a jiffie in case our storage is super slow, this was requested by Andrew. I unfortunately do not have access to a Clariion, so I had to use a ramdisk to represent a super fast array. I tested with a SATA drive with barrier=1 to make sure there was no regression with local disks, I tested with a 4 way multipathed Apple Xserve RAID array and of course the ramdisk. I ran the following command fs_mark -d /mnt/ext3-test -s 4096 -n 2000 -D 64 -t $i where $i was 2, 4, 8, 16 and 32. I mkfs'ed the fs each time.

Quite a few 64-bit architectures are using `long' for their s64/u64 types. We should convert them all to `long long'. Update types.h so we use unsigned long long for u64 and fix all warnings in sparc64 code. Tested with an allnoconfig, defconfig and allmodconfig builds.

We are doing a few changes during 2009 to improve patch handling for drivers/media stuff. Currently, v4l-dvb-maintainer list at linuxtv.org were used to to be v4l/dvb driver maintainers ML, in order to keep track of patch merge requests and to receive bug fixes. This list allows posting for everybody, but, in order to avoid spam, the user subscribe/unsubscribe at the ML is moderated. Other development discussions and end-user forums happened on two separated ML (one for V4L and another for DVB). At the beginning of 2009, we've created linux-media@vger.kernel.org, meaning to be the main upstream development mailing list for drivers/media, including V4L and DVB core and drivers. The choice for vger.kernel.org were due to the fact that most of upstream lists are there. Also, its anti-spam filtering rules are better than what we currently have at linuxtv.org. For now, both video4linux-list and linux-dvb ML will remain active, but more focused on end users. It is expected that those lists will gradually be replaced also by linux-media@vger.kernel.org. This patch reflect those changes at linux MAINTAINERS file. Since the development and bug fix discussions will now happen at linux-media@vger.kernel.org, this patch does the following changes - replaces v4l-dvb-maintainer ML for the new linux-media@vger.kernel.org; - replaces video4linux ML for the new linux-media@vger.kernel.org; While here, it also: - Fixes the existing -git tree entries for drivers/media (since the repository name changed); - Adds the missing drivers/media -git tree entry on a few maintainers entries that don't point to a tree.

| * | V4L/DVB (10190): cx88: Fix some Kbuild troublesMauro Carvalho Chehab2009-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues: drivers/built-in.o: In function `cx88_call_i2c_clients': (.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend' drivers/built-in.o: In function `cx8802_probe': cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend' cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends' With those configs: CONFIG_VIDEO_CX88=y CONFIG_VIDEO_CX88_BLACKBIRD=y CONFIG_VIDEO_CX88_DVB=m CONFIG_DVB_CORE=m After carefully examining the code, with the current code, several cx88 drivers (cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module, if one of them is marked as such. Just fixing Kconfig could create a very complex set of rules. Also, this hides a problem with the current approach where the dvb functionality weren't confined inside dvb module. What happens is that: - cx88-i2c (part of cx8800) has some special rules if DVB; - cx88-mpeg (cx8802 module) has also part of DVB init code; - cx88-dvb has the rest of the dvb code; - cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not. So, instead of doing some tricks at Kconfig and wait for a next breakage, this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb. Another problem is that cx8802 were being compiled, even without cx88-dvb and cx88-blackbird modules. While on this code, let's fix also a reported problem: http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html A solution for the issue were proposed here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect and solve the issues.
