sys/ufs/ffs ffs_vfsops.c
Log:
In ffs_mountffs(), set mnt_iosize_max to si_iosize_max unconditionally
provided the latter is nonzero. At this point, the former is a fairly
arbitrary default value (DFTPHYS), so changing it to any reasonable
value specified by the device driver is safe. Using the maximum of
these limits broke ffs clustered i/o for devices whose si_iosize_max
is < DFLTPHYS. Using the minimum would break device drivers' ability
to increase the active limit from DFTLPHYS up to MAXPHYS.
Copied the code for this and the associated (unnecessary?) fixup of
mp_iosize_max to all other filesystems that use clustering (ext2fs and
msdosfs). It was completely missing.
