I checked a few samples what's the type of the flags, there are unsigned types while the proposed VFS functions take signed type. > +int vfs_ioc_setflags_check(struct inode *inode, int oldflags, int flags); Specifically ext4 uses unsigned type and his was the original API that got copied so I'd think that it should unsigned everywhere. > fs/btrfs/ioctl.c | 13 +++++-------- For the btrfs bits Acked-by: David Sterba <dsterba@xxxxxxxx> and besides the signedness, the rest of the changes look good to me.
