Dear kernelnewbies subscribers,
I was reading the kernel source tree in an attempt to understand how the chroot syscall workes. (I was using the linux-6.17-rc3 tarball from kernel.org.)
At line 1429 of the fs/open.c file, inside the definition of the do_sys_openat2() function getname() is called.
I am having trouble finding its definition.
In particular, $ grep -rn 'getname' fs doesn't return a line like 'struct file *getname (args)' or similar, as I would expect.
Can someone point me to the file/line where getname() is defined?
Thank you, Vulturus

Looks like it's an inline function defined in a header in /include/linux/fs.h: https://elixir.bootlin.com/linux/v6.17-rc3/source/include/linux/fs.h#L2916 Bootlin is a fantastic tool to find where things are defined in the kernel. -Daniel
