This is used by journald to add disk ID information to the journal entry. This re-worked change is from a different patch series and utilizes the following suggestions. - Reduce indentation level (Andy Shevchenko) - Remove unneeded () for conditional operator (Sergei Shtylyov) Signed-off-by: Tony Asleson --- fs/buffer.c | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) base-commit: bbf5c979011a099af5dc76498918ed7df445635b diff --git a/fs/buffer.c b/fs/buffer.c index 50bbc99e3d96..18175fbb1101 100644 --- a/fs/buffer.c +++ b/fs/buffer.c @@ -125,10 +125,17 @@ EXPORT_SYMBOL(__wait_on_buffer); static void buffer_io_error(struct buffer_head *bh, char *msg) { - if (!test_bit(BH_Quiet, &bh->b_state)) - printk_ratelimited(KERN_ERR - "Buffer I/O error on dev %pg, logical block %llu%s\n", - bh->b_bdev, (unsigned long long)bh->b_blocknr, msg); + struct device *gendev; + + if (test_bit(BH_Quiet, &bh->b_state)) + return; + + gendev = bh->b_bdev->bd_disk ? + disk_to_dev(bh->b_bdev->bd_disk) : NULL; + + dev_err_ratelimited(gendev, + "Buffer I/O error, logical block %llu%s\n", + (unsigned long long)bh->b_blocknr, msg); } /*
