This patch is a preparation necessary to remove the BKL from do_new_mount(). It explicitly adds calls to lock_kernel()/unlock_kernel() around get_sb/fill_super operations for filesystems that still uses the BKL. I've read through all the code formerly covered by the BKL inside do_kern_mount() and have satisfied myself that it doesn't need the BKL any more. do_kern_mount() is already called without the BKL when mounting the rootfs and in nfsctl. do_kern_mount() calls vfs_kern_mount(), which is called from various places without BKL: simple_pin_fs(), nfs_do_clone_mount() through nfs_follow_mountpoint(), afs_mntpt_do_automount() through afs_mntpt_follow_link(). Both later functions are actually the filesystems follow_link inode operation. vfs_kern_mount() is calling the specified get_sb function and lets the filesystem do its job by calling the given fill_super function. Therefore I think it is safe to push down the BKL from the VFS to the low-level filesystems get_sb/fill_super operation.

Quota on UDF is non-functional at least since 2.6.16 (I'm too lazy to do more archeology) because it does not provide .quota_write and .quota_read functions and thus quotaon(8) just returns EINVAL. Since nobody complained for all those years and quota support is not even in UDF standard just nuke it. Signed-off-by: NJan Kara <jack@suse.cz>

Currently the VFS calls into the quotactl interface for unmounting filesystems. This means filesystems with their own quota handling can't easily distinguish between user-space originating quotaoff and an unount. Instead move the responsibily of the unmount handling into the filesystem to be consistent with all other dquot handling. Note that we do call dquot_disable a lot later now, e.g. after a sync_filesystem. But this is fine as the quota code does all its writes via blockdev's mapping and that is synced even later.

Currently do_remount_sb calls into the dquot code to tell it about going from rw to ro and ro to rw. Move this code into the filesystem to not depend on the dquot code in the VFS - note ocfs2 already ignores these calls and handles remount by itself. This gets rid of overloading the quotactl calls and allows to unify the VFS and XFS codepaths in that area later.

VAT inode is located in the last block recorded block of the medium. When the drive errorneously reports number of recorded blocks, we failed to load the VAT inode and thus mount the medium.

Move BKL into ->put_super from the only caller. A couple of filesystems had trivial enough ->put_super (only kfree and NULLing of s_fs_info + stuff in there) to not get any locking: coda, cramfs, efs, hugetlbfs, omfs, qnx4, shmem, all others got the full treatment. Most of them probably don't need it, but I'd rather sort that out individually. Preferably after all the other BKL pushdowns in that area. [AV: original used to move lock_super() down as well; these changes are removed since we don't do lock_super() at all in generic_shutdown_super() now] [AV: fuse, btrfs and xfs are known to need no damn BKL, exempt] Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: NMartin K.

We update information in logical volume integrity descriptor after each allocation (as LVID contains free space, number of directories and files on disk etc.). If the filesystem is on some phase change media, this leads to its quick degradation as such media is able to handle only 10000 overwrites or so. We solve the problem by writing new information into LVID only on umount, remount-ro and sync. This solves the problem at the price of longer media inconsistency (previously media became consistent after pdflush flushed dirty LVID buffer) but that should be acceptable.

Anchor block can be located at several places on the medium. Two of the locations are relative to media end which is problematic to detect. Also some drives report some block as last but are not able to read it or any block nearby before it. So let's first try block 256 and if it is all fine, don't look at other possible locations of anchor blocks to avoid IO errors. This change required a larger reorganization of code but the new code is hopefully more readable and definitely shorter. Signed-off-by: NJan Kara <jack@suse.cz>

This patch makes the UDF FS driver use the hardware sector size as the default logical block size, which is required by the UDF specifications. While the previous default of 2048 bytes was correct for optical disks, it was not for hard disks or USB storage devices, and made it impossible to use such a device with the default mount options. (The Linux mkudffs tool uses a default block size of 2048 bytes even on devices with smaller hardware sectors, so this bug is unlikely to be noticed unless UDF-formatted USB storage devices are exchanged with other OSs.) To avoid regressions for people who use loopback optical disk images or who used the (sometimes wrong) defaults of mkudffs, we also try with a block size of 2048 bytes if no anchor was found with the hardware sector size.

Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble.
