Subject: xfs: use bt_nr_sectors in xfs_dax_translate_range
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6ef2175fce30ccab80d519f2afcc93d8b138c16c;p=thirdparty%2Fkernel%2Fstable.git

xfs: use bt_nr_sectors in xfs_dax_translate_range

Only ranges inside the file system can be translated, and the file system
can be smaller than the containing device.

Fixes: f4ed93037966 ("xfs: don't shut down the filesystem for media failures beyond end of log")
