reiserfs_file_write: item has been moved

reiserfs_file_write: item has been moved

[Adrian Phillips]

I got one of these in my logs :-

kernel: reiserfs_file_write: item has been moved while we were in copy_from_user (appending to the direct item)

No other messages in the kern.log, using :-

Linux dusk 2.2.20pre2 #1 Tue Jun 26 11:50:29 CEST 2001 i686 unknown

linux-2.2.19-reiserfs-3.5.34-patch.bz2
linux-2.2.19-reiserfs-3.5.32-buffer-300.patch
linux-2.2.18-rawio.patch  # For LVM
lvm-1.0.1-2.2.20.patch
ide.2.2.19.05042001.patch.bz2 # New IDE for 2.2
max_tasks.patch  # Increases max_tasks to 2048

I couldn't find this mentioned in google, but is this a warning,
serious ?

Thanks for any help,

Sincerely,

Adrian Phillips

These are safe.  Recent 2.2.x kernels include a patch from andrea that
makes copy_from/to_user much more likely to schedule.  Whoever coded
reiserfs_file_write correctly realized it was possible for these calls
to schedule (and correctly dealt with it), but before they almost never
did schedule, so the debugging was probably forgotten.
