+Subject: [PATCH] os/bluestore: use direct write in
+ BlueStore::_write_bdev_label
+
+On AArch64 with kernel page size 64K, it occurs occasionally
+"OSD::init(): unable to read osd superblock" when deploying osd.
+As bluestore use direct write to write the superblock at 0x2000~1000
+and BlueStore::_write_bdev_label use buffer write to write label at
+0x0~1000, The OS flush the buffer write algined to page size, it will
+overwrite the superblock(0x2000~1000). Use driect write to avoid
+overwriting the superblock.
+
+Fixes: https://tracker.ceph.com/issues/57537
