Input/output information processing method and device and electronic equipment

The invention discloses an input/output information processing method and device and electronic equipment. The method comprises the steps that an input/output I/O information write-in request sent by a target application is received, the I/O information write-in request at least comprises a target block device name and first storage capacity, and the first storage capacity is the capacity needed by a block device to write I/O information into a circular buffer area; comparing the first storage capacity with the residual capacity of the circular buffer area; under the condition that the first storage capacity is smaller than or equal to the residual capacity, determining a target block device corresponding to the target block device name from the plurality of block devices; and writing the I/O information into a circular buffer corresponding to the first storage capacity based on the target block device. The technical problem that in the prior art, due to the fact that the I/O information of the block devices
