[Qemu-devel] [PATCH v2 00/13] vvfat: misc fixes for read-only mode

[Hervé Poussineau]

Hi,

This patchset fixes some of issues I encountered when trying to use vvfat, and 
fixes
bug #1599539: https://bugs.launchpad.net/qemu/+bug/1599539

Patch 1 fixes a crash when using 'qemu-img convert'.
Patches 2 to 6 are code cleanup. No functionnal changes.
Patches 7 to 13 fix problems detected by disk checking utilities in read-only 
mode.

With these patches, vvfat creates valid FAT volumes and can be used with QEMU 
disk utilities.

Read-write mode is still buggy after this patchset, but at least, I was not
able to crash QEMU anymore.

Note that patch 2 doesn't pass checkpatch.pl, as it changes indentation only.

Hervé
