From f73ca1b76c6880b934d3ef566c1592efc80bb759 Mon Sep 17 00:00:00 2001 From: David Chinner Date: Wed, 10 Jan 2007 23:15:41 -0800 Subject: [PATCH] Revert bd_mount_mutex back to a semaphore Revert bd_mount_mutex back to a semaphore so that xfs_freeze -f /mnt/newtest; xfs_freeze -u /mnt/newtest works safely and doesn't produce lockdep warnings. (XFS unlocks the semaphore from a different task, by design. The mutex code warns about this) Signed-off-by: Dave Chinner Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/linux/fs.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include/linux/fs.h') diff --git a/include/linux/fs.h b/include/linux/fs.h index 14a337cc346..1410e5330c8 100644 --- a/include/linux/fs.h +++ b/include/linux/fs.h @@ -459,7 +459,7 @@ struct block_device { struct inode * bd_inode; /* will die */ int bd_openers; struct mutex bd_mutex; /* open/close mutex */ - struct mutex bd_mount_mutex; /* mount mutex */ + struct semaphore bd_mount_sem; struct list_head bd_inodes; void * bd_holder; int bd_holders; -- cgit v1.2.3-70-g09d2
