From a051f71ce97c53cde3ac64de64eb02d658d9308e Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Mon, 6 Feb 2012 15:14:40 -0500 Subject: 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.
