  "message": "writeback: fix time ordering of the per superblock dirty inode lists 7\n\nThis one fixes four bugs.\n\nThere are a few situation in there where writeback decides it is going to skip\nover a blockdev inode on the kernel-internal blockdev superblock.  It\npresently does this by moving the blockdev inode onto the tail of the blockdev\nsuperblock\u0027s s_dirty.  But\n\na) this screws up s_dirty\u0027s reverse-time-orderedness and\n\nb) refiling the blockdev for writeback in another 30 second is rude.  We\n   should try again sooner than that.\n\nFix all this up by using redirty_head(): move the blockdev inode onto the head\nof the blockdev superblock\u0027s s_dirty list for prompt writeback.\n\nCc: Mike Waychison \u003cmikew@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
