src/sys/ufs/ffs: ffs_vfsops.c
Log Message:
In fact, we need to sanitize the superblock *after* swapping it. Therefore,
move the swap code inside the loop.
'fs->fs_sbsize' is swapped twice: the first time in order to get the
correct superblock size, and later when swapping the whole superblock
structure. As a result, we need to check 'fs->fs_sbsize' twice.
This:
- fixes my previous changes for swapped FSes
- allows the kernel to look for other superblock locations if the
current superblock is not validated
And now:
- ffs_superblock_validate() takes only one argument: the fs structure
- 'fs_bsize' is unused, so delete it
Add some comments to explain a bit what we are doing.
