  "message": "splice: add helpers for locking pipe inode\n\nThere are lots of sequences like this, especially in splice code:\n\n\tif (pipe-\u003einode)\n\t\tmutex_lock(\u0026pipe-\u003einode-\u003ei_mutex);\n\t/* do something */\n\tif (pipe-\u003einode)\n\t\tmutex_unlock(\u0026pipe-\u003einode-\u003ei_mutex);\n\nso introduce helpers which do the conditional locking and unlocking.\nAlso replace the inode_double_lock() call with a pipe_double_lock()\nhelper to avoid spreading the use of this functionality beyond the\npipe code.\n\nThis patch is just a cleanup, and should cause no behavioral changes.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n",
