[PATCH 016/102] xfs: clean up xfs_ioerror_alert

Dave Chinner
2012-08-23T05:02:48Z

From: Christoph Hellwig <hch@infradead.org>

Upstream commit: 901796afca0d31d97bf6d1bf2ab251a93a4b8c83

Instead of passing the block number and mount structure explicitly
get them off the bp and fix make the argument order more natural.

Also move it to xfs_buf.c and stop printing the device name given
that we already get the fs name as part of xfs_alert, and we know
what device is operates on because of the caller that gets printed,
finally rename it to xfs_buf_ioerror_alert and pass __func__ as
argument where it makes sense.
