24f48416df fs: avoid possible NULL dereference in fs_devread 
It is unwise to first dereference a variable
and then to check if it was NULL.

5994e8b643 fs: Create a common fs_devread for ext4/reiserfs/zfs 
The ext4, reiserfs and zfs filesystems all have their own implementation
of the same function, *_devread. Generalize this function into fs_devread
and put the code into fs/fs_internal.c.
