[PATCH 6.1 -stable] ublk: remove check IO_URING_F_SQE128 in ublk_ch_uring_cmd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



commit 9c7c4bc986932218fd0df9d2a100509772028fb1 upstream

sizeof(struct ublksrv_io_cmd) is 16bytes, which can be held in 64byte SQE,
so not necessary to check IO_URING_F_SQE128.

With this change, we get chance to save half SQ ring memory.
