  "message": "skip writing data pages when inode is under I_SYNC\n\nSince I_SYNC was split out from I_LOCK, the concern in commit\n4b89eed93e0fa40a63e3d7b1796ec1337ea7a3aa (\"Write back inode data pages\neven when the inode itself is locked\") is not longer valid.\n\nWe should revert to the original behavior: in __writeback_single_inode(),\nwhen we find an I_SYNC-ed inode and we\u0027re not doing a data-integrity sync,\nskip writing entirely.  Otherwise, we are double calling do_writepages()\n\nSigned-off-by: Qi Yong \u003cqiyong@fc-cn.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Joern Engel \u003cjoern@wohnheim.fh-wedel.de\u003e\nCc: WU Fengguang \u003cwfg@mail.ustc.edu.cn\u003e\nCc: Michael Rubin \u003cmrubin@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
