Re: [PATCH v3 2/2] dmabuf: Add dmabuf inode number to /proc/*/fdinfo

On 2/4/21 6:23 PM, Kalesh Singh wrote:

If a FD refers to a DMA buffer add the DMA buffer inode number to /proc/<pid>/fdinfo/<FD> and /proc/<pid>/task/<tid>/fdindo/<FD>.

The dmabuf inode number allows userspace to uniquely identify the buffer and avoids a dependency on /proc/<pid>/fd/* when accounting per-process DMA buffer sizes.
