CVS commit: src

Module Name:    src
Committed By:   perseant
Date:           Thu Feb 16 02:47:56 UTC 2012

Modified Files:
        src/sbin/newfs_lfs: make_lfs.c
        src/sys/ufs/lfs: lfs.h lfs_alloc.c lfs_bio.c lfs_segment.c lfs_vfsops.c
        src/tests/fs/vfs: t_renamerace.c t_rmdirrace.c

Log Message:
Pass t_renamerace and t_rmdirrace tests.

Adapt dholland@'s fix to ufs_rename to fix PR kern/43582.  Address several
other MP locking issues discovered during the course of investigating the
same problem.

Removed extraneous vn_lock() calls on the Ifile, since the Ifile writes
are controlled by the segment lock.

Fix PR kern/45982 by deemphasizing the estimate of how much metadata
will fill the empty space on disk when the disk is nearly empty
(t_renamerace crates a lot of inode blocks on a tiny empty disk).
