2005-11-07[PATCH] saner handling of auto_acct_off() and DQUOT_OFF() in umountAl Viro
The way we currently deal with quota and process accounting that might keep vfsmount busy at umount time is inherently broken; we try to turn them off just in case (not quite correctly, at that) and a) pray umount doesn't fail (otherwise they'll stay turned off) b) pray nobody doesn anything funny just as we turn quota off Moreover, LSM provides hooks for doing the same sort of broken logics. The proper way to deal with that is to introduce the second kind of reference to vfsmount. Semantics: - when the last normal reference is dropped, all special ones are converted to normal ones and if there had been any, cleanup is done. - normal reference can be cloned into a special one - special reference can be converted to normal one; that's a no-op if we'd already passed the point of no return (i.e. mntput() had converted special references to normal and started cleanup). The way it works: e.g. starting process accounting converts the vfsmount reference pinned by the opened file into special one and turns it back to normal when it gets shut down; acct_auto_close() is done when no normal references are left. That way it does *not* obstruct umount(2) and it silently gets turned off when the last normal reference to vfsmount is gone. Which is exactly what we want... The same should be done by LSM module that holds some internal references to vfsmount and wants to shut them down on umount - it should make them special and security_sb_umount_close() will be called exactly when the last normal reference to vfsmount is gone. quota handling is even simpler - we don't use normal file IO anymore, so there's no need to hold vfsmounts at all. DQUOT_OFF() is done from deactivate_super(), where it really belongs. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular code will use any of them, re-adding will be trivial. Modular ISAPnP might be interesting in some cases, but this is more legacy code. If someone would work on it to sort all the issues out (starting with the point that most users of __ISAPNP__ will have to be fixed) re-enabling the required EXPORT_SYMBOL's won't be hard for him.

Add new entries for Mystique AGP with the PCI ID 0x051e. I don't actually have such boards but according to google they do exist. Curiosly X.Org doesn't recognize that PCI ID. And what's even more interesting is that Matrox's own Windows drivers don't recognize it either. After going through about a dozen different versions I did find one older driver that does list this particular ID. It is also listed in the pci.ids file. I'm not sure if non-220 AGP chips exist.

2005-11-07[PATCH] fbdev: fix the fb_find_nearest_mode() functionMichal Januszewski
Currently the fb_find_nearest_mode() function finds a mode with screen resolution closest to that described by the 'var' argument and with some arbitrary refresh rate (eg. in the following sequence of refresh rates: 70 60 53 85 75, 53 is selected). This patch fixes the function so that it looks for the closest mode as far as both resolution and refresh rate are concerned. The function's first argument is changed to fb_videomode so that the refresh rate can be specified by the caller, as fb_var_screeninfo doesn't have any fields that could directly hold this data.

2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

2005-11-07[PATCH] ipmi: use refcount in message handlerCorey Minyard
This patch is rather large, but it really can't be done in smaller chunks easily and I believe it is an important change. This has been out and tested for a while in the latest IPMI driver release. There are no functional changes, just changes as necessary to convert the locking over (and a few minor style updates). The IPMI driver uses read/write locks to ensure that things exist while they are in use. This is bad from a number of points of view. This patch removes the rwlocks and uses refcounts and RCU lists to manage what the locks did.
