Modified Files: src/sys/fs/msdosfs [netbsd-6]: msdosfs_fat.c Log Message: 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 -> bio_doread 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.
