[Xen-devel] [PATCH]fix losetup -r flag when sharing disk
hi keir,
this small patch fixes the losetup -r flag when we specify
''w!'' to the disk mode.
the mode from canonicalise_mode can be ''r''
''w'' or ''!''. ian''s patch
doesn''t consider
the ''!'' case.
when I specify ''w!'' to a disk mode, will results disk setup
failure.
log in /var/log/xen/xen-hotplug.log:
[--snip--]
losetup: invalid option -- !
usage:
losetup loop_device # give info
losetup -d loop_device # delete
losetup -f # find unused
losetup -a # list all used
losetup -r # read-only loop
losetup [-e encryption] [-o offset] [-r] {-f|loop_device} file # setup
xenstore-read: couldn''t read path backend/vbd/1/768/node
[--snip--]
ian, please confirm.
this patch should apply to xen-unstable and xen-3.2-testing as well.
regards,
zhigang
