Hi Manish,
vfs_readdir is called by "sys_getdents" system call. Both are in fs/readdir.c.
So the flow of control is something like this -
$ ls ---> readdir () [implemented by C library]
C lib 'readdir' does sth like this -
till you read all dir entries -
issue a syscall to invoke 'sys_getdents' to read further entries of dir.
Thus C lib implementation of readdir repeatedly issues a system call to read a particular dir i.e. the loop you are looking for is in C lib implementation of readdir.
This may also be helpful - http://www.fsl.cs.sunysb.edu/docs/wrapfs/node3.html
Section - 3.3 File Names and Directory Reading
Hope it helps.
Thanks -

Hi sahlot,
Yeah, I tried on this list, but didn't get answer sometimes, so I
thought if there is any file systems specific list since my questions
are mostly related to it. Below are the urls of my previous unanswered
questions.
