2006-03-25[PATCH] mm: restore vm_normal_page checkNick Piggin
Hugh is rightly concerned that the CONFIG_DEBUG_VM coverage has gone too far in vm_normal_page, considering that we expect production kernels to be shipped with the option turned off, and that the code has been under some large changes recently.

2006-03-25[PATCH] direct-io: bug fix in dio handling write errorChen, Kenneth W
There is a bug in direct-io on propagating write error up to the higher I/O layer. When performing an async ODIRECT write to a block device, if a device error occurred (like media error or disk is pulled), the error code is only propagated from device driver to the DIO layer. The error code stops at finished_one_bio(). The aysnc write, however, is supposedly have a corresponding AIO event with appropriate return code (in this case -EIO). Application which waits on the async write event, will hang forever since such AIO event is lost forever (if such app did not use the timeout option in io_getevents call. Regardless, an AIO event is lost). The discovery of above bug leads to another discovery of potential race window with dio->result. The fundamental problem is that dio->result is overloaded with dual use: an indicator of fall back path for partial dio write, and an error indicator used in the I/O completion path. In the event of device error, the setting of -EIO to dio->result clashes with value used to track partial write that activates the fall back path. It was also pointed out that it is impossible to use dio->result to track partial write and at the same time to track error returned from device driver. Because direct_io_work can only determines whether it is a partial write at the end of io submission and in mid stream of those io submission, a return code could be coming back from the driver. Thus messing up all the subsequent logic. Proposed fix is to separating out error code returned by the IO completion path from partial IO submit tracking. A new variable is added to dio structure specifically to track io error returned in the completion path.

2006-03-25[PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget optionsPhillip Susi
As Pekka Enberg pointed out, with the if still following the else, you can still get a null uid written to the disk if you specify a default uid= without uid=forget. In other words, if the desktop user is uid=1000 and the mount option uid=1000 is given ( which is done on ubuntu automatically and probably other distributions that use hal ), then if any other user besides uid 1000 owns a file then a 0 will be written to the media as the owning uid instead.

2006-03-25[PATCH] Ext2 flags shouldn't report "nogrpid"Rob Landley
If I mount ext2 "rw", I want it to say "rw", not "rw,nogrpid". I caught this writing an automated regression test script for the busybox mount command. The symptom is /dev/loop0 on /images/ext2.dir type ext2 (rw,nogrpid) instead of: /dev/loop0 on /images/ext2.dir type ext2 (rw) The behavior was introduced by git commit 8fc2751beb0941966d3a97b26544e8585e428c08.
