[Announce] ploop 1.6

[Kir Kolyshkin]

OpenVZ project has released a new ploop version.
Read below for more information.


Compatibility notes
===================
* this version requires statically built resize2fs, available from 
OpenVZ repository (e2fsprogs-resize2fs-static rpm)
* if you have ploop packages installed on a RHEL5 (CentOS 5) system, 
please remove those manually. ploop is only supported on RHEL6-based kernels


Changes
=======
(since version 1.5)

New functionality:
* offline image shrink support
* tools: added snapshot-list functionality
* extend switch snapshot functionality: ploop_switch_snapshot_ex()
* ploop.spec: disable udev iosched config for ploop devices
* ploop list: added functionality to list mount points

Bug fixes:
* ploop_mount_fs(): use mount_data for first mount
* ploop_mount(): do not allow to use ploop on fs w/o extents
* ploop_{create,resize}_image(): fixed size checks and rounding
* ploop_create_image(): fix memory leak on error path
* ploop_get_info(): fix reported disk size after switching snapshot
* ploop_get_info(): fix when ploop device is not mounted
* ploop_{umount,resize}_image() and many other functions and tools: do 
not return -1

Improvements:
* much faster resize when using resize2fs with EXT4_IOC_RESIZE_FS support
* ploop discard: add cancellation support
* ploop_resize_image(): use real blocksize
* parse_xml(): deny processing DiskDescriptor.xml with several <Storage>
* do not auto-generate dynload.h, instead check if it's uptodate
* create_image(): display error message for incorrect parameters case
* introduce/use SYSEXIT_DEV_NOT_MOUNTED and SYSEXIT_FSCK errors
* alloc_diskdescriptor(): log error if calloc() fails
* ploop.spec: require util-linux, e2fsprogs etc.
