Dear folks,

in my work on the SEEK_DATA/SEEK_HOLE lseek() extension i stubbled on the 
following:

Firstly:

miscfs/specfs/specdev.h:111:#define     spec_getattr    genfs_ebadf
miscfs/specfs/specdev.h:123:#define     spec_seek       genfs_nullop

wich i changed to :

miscfs/specfs/specdev.h:123:#define     spec_seek       genfs_seek

to not alter its behaviour.

However, all lseek(fd, 0, SEEK_END) and the likes fail for the size that is 
requested by spec_getattr() is a bad op. Shouldn't spec_getattr() get its 
own function that does recognize its size and make up a profile for a block 
device? On the other hand why is stat(3) working on a device node when 
spec_getattr is a ebadf ? Answer prolly: its not a specfs... but then i'm 
puzzled.

Secondly:

ufs/mfs/mfsnode.h:70:#define    mfs_seek        genfs_badop

Does this mean no seek's are possible on MFS? or is this entry overwritten 
by say UFS?

Puzzled,
Reinoud
