Since we introduced rcu for read side, spin_lock is used only for update. But we always hold cgroup_lock() when update, so spin_lock() is not need. Additional cleanup: 1) include linux/rcupdate.h explicitly 2) remove unused variable cur_devcgroup in devcgroup_update_access() Signed-off-by: NLai Jiangshan <laijs@cn.fujitsu.com> Acked-by: N"Serge E.

Rather than pre-generating the entire text for the "tasks" file each time the file is opened, we instead just generate/update the array of process ids and use a seq_file to report these to userspace. All open file handles on the same "tasks" file can share a pid array, which may be updated any time that no thread is actively reading the array. By sharing the array, the potential for userspace to DoS the system by opening many handles on the same "tasks" file is removed.

A very large directory with many read failures (either due to storage problems, or due to invalid size & blocks from corruption) will generate a printk storm as the filesystem continues to try to read all the blocks. This flood of messages can tie up the box until it is complete - which may be a very long time, especially for very large corrupted values. This is fixed by only reporting the corruption once each time we try to read the directory.

In ordered mode, if a file data buffer being dirtied exists in the committing transaction, we write the buffer to the disk, move it from the committing transaction to the running transaction, then dirty it. But we don't have to remove the buffer from the committing transaction when the buffer couldn't be written out, otherwise it would miss the error and the committing transaction would not abort. This patch adds an error check before removing the buffer from the committing transaction.

If the journal doesn't abort when it gets an IO error in file data blocks, the file data corruption will spread silently. Because most of applications and commands do buffered writes without fsync(), they don't notice the IO error. It's scary for mission critical systems. On the other hand, if the journal aborts whenever it gets an IO error in file data blocks, the system will easily become inoperable. So this patch introduces a filesystem option to determine whether it aborts the journal or just call printk() when it gets an IO error in file data. If you mount a ext3 fs with data_err=abort option, it aborts on file data write error. If you mount it with data_err=ignore, it doesn't abort, just call printk(). data_err=ignore is the default.

We could run into ENOSPC error on ext3, even when there is free blocks on the filesystem. The problem is triggered in the case the goal block group has 0 free blocks , and the rest block groups are skipped due to the check of "free_blocks < windowsz/2". Current code could fall back to non reservation allocation to prevent early ENOSPC after examing all the block groups with reservation on , but this code was bypassed if the reservation window is turned off already, which is true in this case. This patch fixed two issues: 1) We don't need to turn off block reservation if the goal block group has 0 free blocks left and continue search for the rest of block groups. Current code the intention is to turn off the block reservation if the goal allocation group has a few (some) free blocks left (not enough for make the desired reservation window),to try to allocation in the goal block group, to get better locality. But if the goal blocks have 0 free blocks, it should leave the block reservation on, and continues search for the next block groups,rather than turn off block reservation completely. 2) we don't need to check the window size if the block reservation is off. The problem was originally found and fixed in ext4.

When trying to resize a ext3 fs and you run out of reserved gdt blocks, you get an error that doesn't actually tell you what went wrong, it just says that the gdb it picked is not correct, which is the case since you don't have any reserved gdt blocks left. This patch adds a check to make sure you have reserved gdt blocks to use, and if not prints out a more relevant error.

Currently, original metadata buffers are dirtied when they are unfiled whether the journal has aborted or not. Eventually these buffers will be written-back to the filesystem by pdflush. This means some metadata buffers are written to the filesystem without journaling if the journal aborts. So if both journal abort and system crash happen at the same time, the filesystem would become inconsistent state. Additionally, replaying journaled metadata can overwrite the latest metadata on the filesystem partly. Because, if the journal aborts, journaled metadata are preserved and replayed during the next mount not to lose uncheckpointed metadata. This would also break the consistency of the filesystem. This patch prevents original metadata buffers from being dirtied on abort by clearing BH_JBDDirty flag from those buffers. Thus, no metadata buffers are written to the filesystem without journaling.

The read fail ratio is sensitive to the delay between the first byte written and the first byte read; apparently the sensors cannot be rushed. Increasing the minimum wait time, without changing the total wait time, improves the fail ratio from a 8% chance that any of the sensors fails in one read, down to 0.4%, on a Macbook Air. On a Macbook Pro 3,1, the effect is even more apparent. By reducing the number of status polls, the ratio is further improved to below 0.1%. Finally, increasing the total wait time brings the fail ratio down to virtually zero.

On many Macbooks since mid 2007, the Pro, C2D and Air models, applesmc fails to read some or all SMC ports. This problem has various effects, such as flooded logfiles, malfunctioning temperature sensors, accelerometers failing to initialize, and difficulties getting backlight functionality to work properly. The root of the problem seems to be the command protocol. The current code sends out a command byte, then repeatedly polls for an ack before continuing to send or recieve data. From experiments leading to this patch, it seems the command protocol never quite worked or changed so that one now sends a command byte, waits a little bit, polls for an ack, and if it fails, repeats the whole thing by sending the command byte again. This patch implements a send_command function according to the new interpretation of the protocol, and should work also for earlier models.
