buffesr as "const char *buffer" and should use "const char __user *buffer" instead.
This includes:
osd_brw_stats_seq_write
ldiskfs_osd_cache_seq_write
ldiskfs_osd_wcache_seq_write
lprocfs_osd_force_sync_seq_write
ldiskfs_osd_pdo_seq_write
ldiskfs_osd_auto_scrub_seq_write
ldiskfs_osd_full_scrub_ratio_seq_write
ldiskfs_osd_full_scrub_threshold_rate_seq_write
