[英]ioctl call flow in linux kernel
I am trying to understand the call flow of the ioctl call in linux kernel and I have a question - when we call ioctl from userspace, which function or module in linux kernel is responsible to convert this ioctl call to the corresponding ioctl call in the driver . 我知道驅動程序的 ioctl 不會直接從用戶空間調用。 首先調用 go 通過一些 kernel API,然后 ZDB974238714CA8DE634A7CE1D08 將依次調用驅動程序。 請幫我指出 kernel API 將 ioctl 傳輸到合適的驅動程序。
