  "message": "[PATCH] namespace.c: fix mnt_namespace clearing\n\nThis patch clears mnt_namespace on unmount.\n\nNot clearing mnt_namespace has two effects:\n\n   1) It is possible to attach a new mount to a detached mount,\n      because check_mnt() returns true.\n\n      This means, that when no other references to the detached mount\n      remain, it still can\u0027t be freed.  This causes a resource leak,\n      and possibly un-removable modules.\n\n   2) If mnt_namespace is dereferenced (only in mark_mounts_for_expiry())\n      after the namspace has been freed, it can cause an Oops, memory\n      corruption, etc.\n\n1) has been tested before and after the patch, 2) is only speculation.\n\nSigned-off-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nAcked-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
