Minix filesystem until version 2 has a fixed blocksize of 1024 bytes.
|
||||
If you try to create a filsystem on a device with a physical sectorsize
|
||||
larger than 1024 bytes, this resulting minix fs cannot be mounted,
|
||||
because the physical sectorsize must be smaller than the filesystem
|
||||
blocksize.
|
||||
This patch adds a check for this and will refuse to create a filesystem
|
||||
if the sectorsize is bigger than the blocksize.
