  "message": "[PATCH] device-mapper: fix md-\u003elock deadlocks in core\n\nThis patch is an attempt to fix deadlocks discovered in the core dm.\n\nThe problems boil down to md-\u003elock having to be held in too many places, so\nI\u0027ve split it into two: md-\u003esuspend_lock and md-\u003eio_lock.\n\nsuspend_lock is now held throughout dm_suspended() as well as dm_resume()\nand dm_swap_table() so that these functions cannot run concurrently:\nthere\u0027s no requirement for that and it added complexity.\n\nDMF_FS_LOCKED becomes redundant: DMF_SUSPENDED provides adequate\nprotection.\n\nSigned-Off-By: Alasdair G Kergon \u003cagk@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
