Hitoshi Mitake 498f21405a sheepdog: use per AIOCB dirty indexes for non overlapping requests ... In the commit 96b14ff85acf, requests for overlapping areas are serialized. However, it cannot handle a case of non overlapping requests. In such a case, min_dirty_data_idx and max_dirty_data_idx can be overwritten by the requests and invalid inode update can happen e.g. a case like create(1, 2) and create(3, 4) are issued in parallel. This patch lets SheepdogAIOCB have dirty data indexes instead of BDRVSheepdogState for avoiding the above situation. This patch also does trivial renaming for better description: overwrapping -> overlapping Cc: Teruaki Ishizaki <ishizaki.teruaki@lab.ntt.co.jp> Cc: Vasiliy Tolstov <v.tolstov@selfip.ru> Cc: Jeff Cody <jcody@redhat.com> Signed-off-by: Hitoshi Mitake <mitake.hitoshi@lab.ntt.co.jp> Tested-by: Vasiliy Tolstov <v.tolstov@selfip.ru> Message-id: 1441076590-8015-2-git-send-email-mitake.hitoshi@lab.ntt.co.jp Signed-off-by: Jeff Cody <jcody@redhat.com>		2015-09-25 10:25:19 -04:00
