| * quota: Improve checking of quota file headerJan Kara2009-12-23
| | | | | | | | | | | | | | | | When we are asked for vfsv0 quota format and the file is in vfsv1 format (or vice versa), refuse to use the quota file. Also return with error when we don't like the header of quota file. Signed-off-by: Jan Kara <jack@suse.cz>

| * ext3: ext3_mark_recovery_complete() doesn't need to use lock_superEric Sandeen2009-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function ext3_mark_recovery_complete() is called from two call paths: either (a) while mounting the filesystem, in which case there's no danger of any other CPU calling write_super() until the mount is completed, and (b) while remounting the filesystem read-write, in which case the fs core has already locked the superblock. This also allows us to take out a very vile unlock_super()/lock_super() pair in ext3_remount(). Port of ext4 commit a63c9eb2ce6f5028da90f282798232c4f398ceb8 by Theodore Ts'o <tytso@mit.edu>.

| * quota: decouple fs reserved space from quota reservationDmitry Monakhov2009-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently inode_reservation is managed by fs itself and this reservation is transfered on dquot_transfer(). This means what inode_reservation must always be in sync with dquot->dq_dqb.dqb_rsvspace. Otherwise dquot_transfer() will result in incorrect quota(WARN_ON in dquot_claim_reserved_space() will be triggered) This is not easy because of complex locking order issues for example http://bugzilla.kernel.org/show_bug.cgi?id=14739 The patch introduce quota reservation field for each fs-inode (fs specific inode is used in order to prevent bloating generic vfs inode). This reservation is managed by quota code internally similar to i_blocks/i_bytes and may not be always in sync with internal fs reservation. Also perform some code rearrangement: - Unify dquot_reserve_space() and dquot_reserve_space() - Unify dquot_release_reserved_space() and dquot_free_space() - Also this patch add missing warning update to release_rsv() dquot_release_reserved_space() must call flush_warnings() as dquot_free_space() does.

| | * | drm/radeon/kms: add cvt mode if we only have lvds w/h and no edid (v4)Alex Deucher2009-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes LVDS on some mac laptops without a panel edid. v2 - Set proper mode type flags v3 - Note that this is not neceesarily the exact panel mode, but an approximation based on the cvt formula. For these systems we should ideally read the mode info out of the registers or add a mode table, but this works and is much simpler. v4 - Update comments and debug message.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if there was no firmware available, the DRM would just disable channel creation from userspace, but still use a single channel for its own purposes. With a bit of care it should actually be possible to do this, due to the DRM's very limited use of the engine. It currently doesn't work correctly however, resulting in corrupted fbcon and hangs on a number of cards. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

There's notes in nv40_grctx.c explaining most of the things we don't implement. If we discover if/why any of it is required further down the track, we'll handle it then. The PGRAPH state generated for each chipset should match what NVIDIA do almost exactly (there's a couple of exceptions). If someone has a lot of time on their hands, they could figure out the mapping of object/method to PGRAPH register and demagic the initial state a little, it's not terribly important however. At time of commit, confirmed to be working at least well enough for accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46, NV49, NV4A, NV4B and NV4E. A module option has been added to force the use of external firmware blobs if it becomes required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
