From ed8a9d2c816e0b0a2c5a605505e0f09ae9010dd6 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Fri, 20 Nov 2015 22:18:43 +0100 Subject: block: use bd{grab,put}() instead of open-coding - bd_acquire() and bd_forget() open-code bdgrab() and bdput() - raw driver uses igrab() but never checks its return value and always holds another ref from bind_set() while calling it, so it's equivalent to bdgrab() Signed-off-by: Ilya Dryomov Signed-off-by: Jens Axboe --- fs/block_dev.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'fs') diff --git a/fs/block_dev.c b/fs/block_dev.c index aa1a45985889..8b02c90ced87 100644 --- a/fs/block_dev.c +++ b/fs/block_dev.c @@ -696,7 +696,7 @@ static struct block_device *bd_acquire(struct inode *inode) spin_lock(&bdev_lock); bdev = inode->i_bdev; if (bdev) { - ihold(bdev->bd_inode); + bdgrab(bdev); spin_unlock(&bdev_lock); return bdev; } @@ -712,7 +712,7 @@ static struct block_device *bd_acquire(struct inode *inode) * So, we can access it via ->i_mapping always * without igrab(). */ - ihold(bdev->bd_inode); + bdgrab(bdev); inode->i_bdev = bdev; inode->i_mapping = bdev->bd_inode->i_mapping; list_add(&inode->i_devices, &bdev->bd_inodes); @@ -735,7 +735,7 @@ void bd_forget(struct inode *inode) spin_unlock(&bdev_lock); if (bdev) - iput(bdev->bd_inode); + bdput(bdev); } /** -- cgit v1.2.3
