allow_signal() checks ->mm == NULL. Not sure why. Perhaps to make sure current is the kernel thread. But this helper must not be used unless we are the kernel thread, kill this check.

Try to fix memcg's lru rotation sanity: make memcg use the same logic as the global LRU does. Now, at __isolate_lru_page() retruns -EBUSY, the page is rotated to the tail of LRU in global LRU's isolate LRU pages. But in memcg, it's not handled. This makes memcg do the same behavior as global LRU and rotate LRU in the page is busy.

A user can set memcg.limit_in_bytes == memcg.memsw.limit_in_bytes when the user just want to limit the total size of applications, in other words, not very interested in memory usage itself. In this case, swap-out will be done only by global-LRU. But, under current implementation, memory.limit_in_bytes is checked at first and try_to_free_page() may do swap-out. But, that swap-out is useless for memsw.limit_in_bytes and the thread may hit limit again. This patch tries to fix the current behavior at memory.limit == memsw.limit case. And documentation is updated to explain the behavior of this special case.

This patch fixes mis-accounting of swap usage in memcg. In the current implementation, memcg's swap account is uncharged only when swap is completely freed. But there are several cases where swap cannot be freed cleanly. For handling that, this patch changes that memcg uncharges swap account when swap has no references other than cache. By this, memcg's swap entry accounting can be fully synchronous with the application's behavior. This patch also changes memcg's hooks for swap-out.

Add file RSS tracking per memory cgroup We currently don't track file RSS, the RSS we report is actually anon RSS. All the file mapped pages, come in through the page cache and get accounted there. This patch adds support for accounting file RSS pages. It should 1. Help improve the metrics reported by the memory resource controller 2. Will form the basis for a future shared memory accounting heuristic that has been proposed by Kamezawa. Unfortunately, we cannot rename the existing "rss" keyword used in memory.stat to "anon_rss". We however, add "mapped_file" data and hope to educate the end user through documentation.

The 'noprefix' option was introduced for backwards-compatibility of cpuset, but actually it can be used when mounting other subsystems. This results in possibility of name collision, and now the collision can really happen, because we have 'stat' file in both memory and cpuacct subsystem: # mount -t cgroup -o noprefix,memory,cpuacct xxx /mnt Cgroup will happily mount the 2 subsystems, but only 'stat' file of memory subsys can be seen. We don't want users to use nopreifx, and also want to avoid name collision, so we change to allow noprefix only if mounting just the cpuset subsystem.

Several code paths in reiserfs have a construct like: if (is_direntry_le_ih(ih = B_N_PITEM_HEAD(src, item_num))) ... which, in addition to being ugly, end up causing compiler warnings with gcc 4.4.0. Previous compilers didn't issue a warning. fs/reiserfs/do_balan.c:1273: warning: operation on `aux_ih' may be undefined fs/reiserfs/lbalance.c:393: warning: operation on `ih' may be undefined fs/reiserfs/lbalance.c:421: warning: operation on `ih' may be undefined fs/reiserfs/lbalance.c:777: warning: operation on `ih' may be undefined I believe this is due to the ih being passed to macros which evaluate the argument more than once. This is old code and we haven't seen any problems with it, but this patch eliminates the warnings. It converts the multiple evaluation macros to static inlines and does a preassignment for the cases that were causing the warnings because that code is just ugly.

So far, permissions set via 'mode' and/or 'dmode' mount options were effective only if the medium had no rock ridge extensions (or was mounted without them). Add 'overriderockmode' mount option to indicate that these options should override permissions set in rock ridge extensions. Maybe this should be default but the current behavior is there since mount options were created so I think we should not change how they behave.

As Ted pointed out, it can happen that ext3_truncate() returns without removing inode from orphan list. This way we could in some rare cases (like when we get ENOMEM from an allocation in ext3_truncate called because of failed ext3_write_begin) leave the inode on orphan list and that triggers assertion failure on umount. So make ext3_truncate() always remove inode from in-memory orphan list.

Chain verification in ext3_get_blocks() has been hosed since it called verify_chain(chain, NULL) which always returns success. As a result readers could in theory race with truncate. On the other hand the race probably cannot happen with the current locking scheme, since by the time ext3_truncate() is called all the pages are already removed and hence get_block() shouldn't be called on such pages...

One of our users is complaining that his backup tool is upset on ext2 (while it's happy on ext3, xfs, ...) because of the mtime change. The problem is: mkdir foo mkdir bar mkdir foo/a Now under ext2: mv foo/a foo/b changes mtime of 'foo/a' (foo/b after the move). That does not really make sense and it does not happen under any other filesystem I've seen. More complicated is: mv foo/a bar/a This changes mtime of foo/a (bar/a after the move) and it makes some sense since we had to update parent directory pointer of foo/a. But again, no other filesystem does this. So after some thoughts I'd vote for consistency and change ext2 to behave the same as other filesystems. Do not update mtime of a moved directory. Specs don't say anything about it (neither that it should, nor that it should not be updated) and other common filesystems (ext3, ext4, xfs, reiserfs, fat, ...) don't do it. So let's become more consistent. Spotted by ronny.pretzsch@dfs.de, initial fix by Jörn Engel.

On OpenFirmware platforms, it makes the most sense to get platform_data from the device tree. Make an attempt to translate OF node properties into platform_data struct before bailing out. Note that the implementation approach taken differs from other device drivers that make use of device tree information. This is because I2C chips are already registered automatically by of_i2c, so we can get by with a small translator function in the driver.

Add support for the Epson RX-8025SA/NB RTC chips. It includes support for alarms, periodic interrupts (1 Hz) and clock precision adjustment. For clock precision adjustment, the SYSFS file "clock_adjust_ppb" gets created in "/sys/class/rtc/rtcX/device". It permits to set and get the clock adjustment in ppb (parts per billion), e.g.: # echo -183000 > /sys/class/rtc/rtc0/device/clock_adjust_ppb # cat /sys/class/rtc/rtc0/device/clock_adjust_ppb -183000 This allows to compensate temperature dependent clock drifts. According to the RX8025 SA/NB application manual the frequency and temperature characteristics can be approximated using the following equation: df = a * (ut - t)**2 df: Frequency deviation in any temperature a : Coefficient = (-35 +-5) * 10**-9 ut: Ultimate temperature in degree = +25 +-5 degree t : Any temperature in degree Signed-off-by: NWolfgang Grandegger <wg@grandegger.com> Signed-off-by: NSergei Poselenov <sposelenov@emcraft.com> Signed-off-by: NYuri Tikhonov <yur@emcraft.com> Signed-off-by: NDmitry Rakhchev <rda@emcraft.com> Signed-off-by: NMatthias Fuchs <matthias.fuchs@esd.eu> Acked-by: NJean Delvare <khali@linux-fr.org> Signed-off-by: NAlessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The RTC driver for ds1742 / ds1743 uses a static nvram attribute. This patch replaces this static attribute with one nvram attribute for each ds174x registered. The nvram size is not the same for all types of ds174x. The nvram size is accessible as the file size of the nvram attribute in sysfs. With only a single nvram attribute, this file size will be incorrect if more than one type of ds174x is present on a system. See the comment in the removed code below.
