  "message": "dm raid1: one kmirrord per mirror\n\nThis patch replaces the single instance of kmirrord by one instance per mirror\nset.  This change is required to avoid a deadlock in kmirrord when the\npersistent dirty log of a mirror itself resides on a mirror.  The single\ninstance of kmirrord then issues a sync write to the dirty log in write_bits\nwhich gets deferred to kmirrord itself later in the call chain.  But kmirrord\nnever does the deferred work because it is still waiting for the sync\nwrite_bits.\n\n_mirror_sets is removed as it no longer needed, and we always flush the\nworkqueue before destroying it to ensure all work is complete before\ndestroying it.\n\nSigned-off-by: Holger Smolinski \u003csmolinski@de.ibm.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
