BKL: Explicitly add BKL around get_sb/fill_super

2010-10-04T19:10:10Z

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. [arnd: do not add the BKL to those file systems that already don't use it elsewhere] Signed-off-by: Jan Blunck Signed-off-by: Arnd Bergmann Cc: Matthew Wilcox Cc: Christoph Hellwig

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: (96 commits) no need for list_for_each_entry_safe()/resetting with superblock list Fix sget() race with failing mount vfs: don't hold s_umount over close_bdev_exclusive() call sysv: do not mark superblock dirty on remount sysv: do not mark superblock dirty on mount btrfs: remove junk sb_dirt change BFS: clean up the superblock usage AFFS: wait for sb synchronization when needed AFFS: clean up dirty flag usage cifs: truncate fallout mbcache: fix shrinker function return value mbcache: Remove unused features add f_flags to struct statfs(64) pass a struct path to vfs_statfs update VFS documentation for method changes. All filesystems that need invalidate_inode_buffers() are doing that explicitly convert remaining ->clear_inode() to ->evict_inode() Make ->drop_inode() just return whether inode needs to be dropped fs/inode.c:clear_inode() is gone fs/inode.c:evict() doesn't care about delete vs. non-delete paths now ... Fix up trivial conflicts in fs/nilfs2/super.c

udf: Remove dead quota code

2010-05-24T12:10:19Z

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: Jan Kara

quota: rename default quotactl methods to dquot_

2010-05-24T12:10:17Z

Follow the dquot_* style used elsewhere in dquot.c. [Jan Kara: Fixed up missing conversion of ext2] Signed-off-by: Christoph Hellwig Signed-off-by: Jan Kara

quota: explicitly set ->dq_op and ->s_qcop

2010-05-24T12:10:17Z

Only set the quota operation vectors if the filesystem actually supports quota instead of doing it for all filesystems in alloc_super(). [Jan Kara: Export dquot_operations and vfs_quotactl_ops] Signed-off-by: Christoph Hellwig Signed-off-by: Jan Kara

quota: move unmount handling into the filesystem

2010-05-24T12:09:12Z

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.

quota: kill the vfs_dq_off and vfs_dq_quota_on_remount wrappers

2010-05-24T12:06:40Z

Instead of having wrappers in the VFS namespace export the dquot_suspend and dquot_resume helpers directly. Also rename vfs_quota_disable to dquot_disable while we're at it. [Jan Kara: Moved dquot_suspend to quotaops.h and made it inline] Signed-off-by: Christoph Hellwig Signed-off-by: Jan Kara
