dquot: cleanup dquot initialize routine

2010-03-04T23:20:30Z

Get rid of the initialize dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_initialize helper to __dquot_initialize and vfs_dq_init to dquot_initialize to have a consistent namespace.

dquot: move dquot initialization responsibility into the filesystem

2010-03-04T23:20:30Z

Currently various places in the VFS call vfs_dq_init directly. This means we tie the quota code into the VFS. Get rid of that and make the filesystem responsible for the initialization. For most metadata operations this is a straight forward move into the methods, but for truncate and open it's a bit more complicated. For truncate we currently only call vfs_dq_init for the sys_truncate case because open already takes care of it for ftruncate and open(O_TRUNC) - the new code causes an additional vfs_dq_init for those which is harmless. For open the initialization is moved from do_filp_open into the open method, which means it happens slightly earlier now, and only for regular files. The latter is fine because we don't need to initialize it for operations on special files, and we already do it as part of the namespace operations for directories. Add a dquot_file_open helper that filesystems that support generic quotas can use to fill in ->open. Signed-off-by: Christoph Hellwig Signed-off-by: Jan Kara

dquot: cleanup dquot transfer routine

2010-03-04T23:20:29Z

Get rid of the transfer dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_transfer helper to __dquot_transfer and vfs_dq_transfer to dquot_transfer to have a consistent namespace, and make the new dquot_transfer return a normal negative errno value which all callers expect.

dquot: move dquot transfer responsibility into the filesystem

2010-03-04T23:20:28Z

Currently notify_change calls vfs_dq_transfer directly. This means we tie the quota code into the VFS. Get rid of that and make the filesystem responsible for the transfer. Most filesystems already do this, only ufs and udf need the code added, and for jfs it needs to be enabled unconditionally instead of only when ACLs are enabled.

jffs2/jfs/xfs: switch over to 'check_acl' rather than 'permission()'

2009-09-08T18:09:04Z

This avoids an indirect call in the VFS for each path component lookup. Well, at least as long as you own the directory in question, and the ACL check is unnecessary. Reviewed-by: James Morris Acked-by: Serge Hallyn Signed-off-by: Linus Torvalds

BKL-removal: Implement a compat_ioctl handler for JFS

2008-02-07T19:45:29Z

The ioctls were already compatible except for the actual values so this was fairly easy to do. Signed-off-by: Andi Kleen Signed-off-by: Dave Kleikamp

BKL-removal: Use unlocked_ioctl for jfs

2008-02-07T19:33:58Z

Convert jfs_ioctl over to not use the BKL. The only potential race I could see was with two ioctls in parallel changing the flags and losing the updates. Use the i_mutex to protect against this. Signed-off-by: Andi Kleen Signed-off-by: Dave Kleikamp

sendfile: remove .sendfile from filesystems that use generic_file_sendfile()

2007-07-10T06:04:13Z

They can use generic_file_splice_read() instead. Since sys_sendfile() now prefers that, there should be no change in behaviour. Signed-off-by: Jens Axboe

[PATCH] mark struct inode_operations const 2

2007-02-12T17:48:46Z

Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

jfs: Add splice support

2006-10-30T17:47:02Z

This allows the splice() and tee() syscalls to be used with JFS. Signed-off-by: Daniel Drake Signed-off-by: Dave Kleikamp
