a051f71ce9 hfsplus: add an ioctl to bless files
Making an hfsplus partition bootable requires the ability to "bless" a
file by putting its inode number in the volume header. Doing this from
userspace on a mounted filesystem is impractical since the kernel will
write back the original values on unmount. Add an ioctl to allow userspace
to update the volume header information based on the target file.

0347b6e95c hfsplus: change finder_info to u32
The finder_info block in the hfsplus volume header is currently defined as
an array of 8 bit values, but TN1150 defines it as being an array of 32 bit
values. Fix for convenience.

f3922382ce hfsplus: initialise userflags
The userflags field was being written to the filesystem without being
initialised. Make sure it's clear, since otherwise files end up with
garbage attributes.

8f82ecae53 qnx4: get rid of qnx4_bread/qnx4_getblk
pointless, since the only caller will want the physical block

9bcb4b733c vfs: turn generic_drop_inode() into static inline
Once upon a time it used to be much bigger, but these days there's
no point whatsoever keeping it in fs/inode.c, especially since
it's not even needed as initializer for ->drop_inode() - it's the
default and leaving ->drop_inode NULL will do just as well.
