bcache: fix mistaken sysfs entry for io_error counter (54619998) · Commits · 戴 / test

In bch_cached_dev_files[] from driver/md/bcache/sysfs.c, sysfs_errors is incorrectly inserted in. The correct entry should be sysfs_io_errors. This patch fixes the problem and now I/O errors of cached device can be read from /sys/block/bcache<N>/bcache/io_errors. Fixes: ("bcache: add io_disable to struct cached_dev") Signed-off-by:
