Subject: PR/43582 CVS commit: src/tests/fs/vfs
Date: Wed, 14 Jul 2010 21:44:40 +0000

 Module Name:	src
 Committed By:	pooka
 Date:		Wed Jul 14 21:44:40 UTC 2010

 Modified Files:
 	src/tests/fs/vfs: t_renamerace.c

 Log Message:
 xfail test on lfs.  It goes badaboom faster than you can find your
 multipass.  Borrow PR kern/43582 used earlier for rmdirrace, as it
 looks pretty much like the same problem.

 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
 	    lfs_vnops.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).
