btrfs: refactor btrfs_set_prop and add btrfs_set_prop_trans btrfs_set_prop() takes transaction pointer as the first argument, however in ioctl.c for the purpose of setting the compression property, we call btrfs_set_prop() with NULL transaction pointer. Down in the call chain btrfs_setxattr() starts transaction to update the attribute and also to update the inode. So for clarity, create btrfs_set_prop_trans() with no transaction pointer as argument, in preparation to start transaction here instead of doing it down the call chain at btrfs_setxattr(). Also now the btrfs_set_prop() is a static function. Signed-off-by: Anand Jain <anand.jain@oracle.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

fs: new API for handling inode->i_version Add a documentation blob that explains what the i_version field is, how it is expected to work, and how it is currently implemented by various filesystems. We already have inode_inc_iversion. Add several other functions for manipulating and accessing the i_version counter. For now, the implementation is trivial and basically works the way that all of the open-coded i_version accesses work today. Future patches will convert existing users of i_version to use the new API, and then convert the backend implementation to do things more efficiently.

btrfs: Make btrfs_ino take a struct btrfs_inode Currently btrfs_ino takes a struct inode and this causes a lot of internal btrfs functions which consume this ino to take a VFS inode, rather than btrfs' own struct btrfs_inode. In order to fix this "leak" of VFS structs into the internals of btrfs first it's necessary to eliminate all uses of struct inode for the purpose of inode. This patch does that by using BTRFS_I to convert an inode to btrfs_inode. With this problem eliminated subsequent patches will start eliminating the passing of struct inode altogether, eventually resulting in a lot cleaner code.

btrfs: take an fs_info directly when the root is not used otherwise There are loads of functions in btrfs that accept a root parameter but only use it to obtain an fs_info pointer. Let's convert those to just accept an fs_info pointer directly. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

btrfs: pull node/sector/stripe sizes out of root and into fs_info We track the node sizes per-root, but they never vary from the values in the superblock. This patch messes with the 80-column style a bit, but subsequent patches to factor out root->fs_info into a convenience variable fix it up again.

fs: Replace current_fs_time() with current_time() current_fs_time() uses struct super_block* as an argument. As per Linus's suggestion, this is changed to take struct inode* as a parameter instead. This is because the function is primarily meant for vfs inode timestamps. Also the function was renamed as per Arnd's suggestion. Change all calls to current_fs_time() to use the new current_time() function instead. current_fs_time() will be deleted.

btrfs: Switch to generic xattr handlers The btrfs_{set,remove}xattr inode operations check for a read-only root (btrfs_root_readonly) before calling into generic_{set,remove}xattr. If this check is moved into __btrfs_setxattr, we can get rid of btrfs_{set,remove}xattr. This patch applies to mainline, I would like to keep it together with the other xattr cleanups if possible, though. Could you please review?
