src/sys/fs/msdosfs [netbsd-6]: msdosfs_fat.c
Pull up following revision(s) (requested by hannken in ticket #183):
sys/fs/msdosfs/msdosfs_fat.c: revision 1.20
pcbmap(): We cannot use bread() here as for the pagedaemon getblk()
may fail leading to a panic in bread().
Replace bread() with getblk() / VOP_STRATEGY() and return
an error if getblk() fails.
Fixes PR#46282: 6.0_BETA crash: msdosfs_bmap -> pcbmap -> bread ->
This is an interim solution for easy pullup. The final solution
is be to change bread() to not return a buffer on error. As
we have to change all callers of bread() this will not qualify
for a pullup.
