CVS commit: src/sys/ufs/lfs

[Konrad Schroder <perseant%netbsd.org@localhost>]

Module Name:    src
Committed By:   perseant

Modified Files:
        src/sys/ufs/lfs: lfs.h lfs_alloc.c lfs_balloc.c lfs_bio.c lfs_segment.c
            lfs_subr.c lfs_syscalls.c lfs_vfsops.c lfs_vnops.c

Log Message:
Add simple_lock protection for lfs_seglock and lfs_subsys_pages; these will
be expanded to cover other per-fs and subsystem-wide data as well.

Fix a case of IN_MODIFIED being set without updating lfs_uinodes, resulting
in a "lfs_uinodes < 0" panic.

Fix a deadlock in lfs_putpages arising from the need to busy all pages in a
block; unbusy any that had already been busied before starting over.
