--e0cb4efa6e7e2274bc04cb14c789 Content-Type: text/plain; charset=ISO-8859-1 Hello, On behalf of Smartcom Bulgaria AD I would like to contribute a patch for libstand's NANDFS support in FreeBSD. It is related to the correct detection of a superblock when accessing the filesystem. It's also been noticed that the election of a superblock between kernelspace and libstand's one differs regarding the checkpoint number. The patch is attached. Comments will be appreciated.
