With Cal Peake <cp@absolutedigital.net> I've found a typo in drivers/input/gameport/Makefile in kernel 2.6.9 which effectively prevents the CS461x gameport code from being included. Signed-off-by:

Implement quota journaling and quota reading and writing functions for reiserfs. Solves also several other deadlocks possible for reiserfs due to the lock inversion on journal_begin and quota locks. From: Vladimir Saveliev <vs@namesys.com> When CONFIG_QUOTA is defined reiserfs's finish_unfinished sets and clears MS_ACTIVE bit in s_flags field of super block. If that bit was set already it should not be set. Signed-off-by:

Fix possible races between umount and quota on/off. Finally I decided to take a reference to vfsmount during vfs_quota_on() and to drop it after the final cleanup in the vfs_quota_off(). This way we should be all the time guarded against umount. This way was protected also the old code which used filp_open() for opening quota files. I was also thinking about other ways of protection but there would be always a window (provided I don't want to play much with namespace locks) where vfs_quota_on() could be called while umount() is in progress resulting in the "Busy inodes after unmount" messages... Get a reference to vfsmount during quotaon() so that we are guarded against umount (as was the old code using filp_open()). Signed-off-by:

The four patches in this series fix deadlocks with quotas of pagelock (the problem was lock inversion on PageLock and transaction start - quota code needed to first start a transaction and then write the data which subsequently needed acquisition of PageLock while the standard ordering - PageLock first and transaction start later - was used e.g. by pdflush). They implement a new way of quota access to disk: Every filesystem that would like to implement quotas now has to provide quota_read() and quota_write() functions. These functions must obey quota lock ordering (in particular they should not take PageLock inside a transaction). The first patch implements the changes in the quota core, the other three patches implement needed functions in ext2, ext3 and reiserfs. The patch for reiserfs also fixes several other lock inversion problems (similar as ext3 had) and implements the journaled quota functionality (which comes almost for free after the locking fixes...). The quota core patch makes quota support in other filesystems (except XFS which implements everything on its own ;)) unfunctional (quotaon() will refuse to turn on quotas on them). When the patches get reasonable wide testing and it will seem that no major changes will be needed I can make fixes also for the other filesystems (JFS, UDF, UFS). This patch: The patch implements the new way of quota io in the quota core. Every filesystem wanting to support quotas has to provide functions quota_read() and quota_write() obeying quota locking rules. As the writes and reads bypass the pagecache there is some ugly stuff ensuring that userspace can see all the data after quotaoff() (or Q_SYNC quotactl). In future I plan to make quota files inaccessible from userspace (with the exception of quotacheck(8) which will take care about the cache flushing and such stuff itself) so that this synchronization stuff can be removed... The rewrite of the quota core. Quota uses the filesystem read() and write() functions no more to avoid possible deadlocks on PageLock. From now on every filesystem supporting quotas must provide functions quota_read() and quota_write() which obey the quota locking rules (e.g. they cannot acquire the PageLock). Signed-off-by:

Jan Kara authored
Attached patch exposes reiserfs_sync_fs(). This call is needed by the new quota code to write data to disk on quotaoff so that userspace can see them afterwards. Chris Mason agrees with the patch. Make reiserfs provide the sync_fs() function so that the quota code has a way to reliably force a transaction to disk. Signed-off-by:

PT_DTRACE without PT_PTRACED. Long ago, the "D" in PT_DTRACE meant "Delayed", and it was used as a flag to mark that we had ptrace'd the process but no longer did so. That hasn't been true in a while now, and the flag should probably be renamed, but in the meantime the test for PT_PTRACED being cleared had been corrupted into something totally nonsensical. Pointed out by Andi Kleen.

It didn't allocate space for the final terminating entry, which caused it to overwrite the next slab entry, which in turn sometimes ended up being a slab array cache pointer. End result: total slab cache corruption at a random time afterwards. Very nasty.

The latter hunk of the forwarded patch has already been applied, so please apply the patch as it appears in the un-forwarded part. I've taken some liberties in adding the Acked/Signed-off lines in what I hope is an agreeable way.
