Subject: [PATCH 0/3] E2fsprogs: tune2fs: use an ioctl to update mounted fs

Teach tune2fs to try use the new EXT4_IOC_SET_TUNE_SB_PARAM ioctl
interface to update mounted file systems.  This will allow us to
disallow read/write access to the block device while the file system
is mounted, once we are sure the updated e2fsprogs is in use.

Theodore Ts'o (3):
  tune2fs: reorganize command-line flag handling
  tune2fs: rework parse_extended_opts() so it only parses the option
    string
  tune2fs: try to use the SET_TUNE_SB_PARAM ioctl on mounted file
    systems
