hello, 1) how kernel write to /proc entry? while studying kernel source i found that there is no open/read/write/close file functions. what i found is that sprintf function that writes to /proc entry. can anyone please explain it? 2)what is the use of read_write.c file in fs directory of kernel source? the file contains sys_read, sys_write. why there is no function that will read a user space file and write to it. i found few questions asked on linux-kernel as well as kernelnewbies but there is no one able to answer it? i am using kernel 2.4.24. regards, parag.
