Subject: xfs: ratelimit xfs_discard_page messages
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4ab45e259f31cc063805c659e3c203577722b701;p=linux.git

xfs: ratelimit xfs_discard_page messages

Use printk_ratelimit() to limit the amount of messages printed from
xfs_discard_page.  Without that a failing device causes a large
number of errors that doesn't really help debugging the underling
issue.
