How to locate the souce code of this kind of item, vfs_unlink.cold+0x1d/0x55, in linux kernel?
I compiled the linux kernel, 5.10.7 with CONFIG_DEBUG_INFO=y.
Then from dump_stack() inside the kernel, then inside gdb,
l *do_unlinkat+0x1b0 can locate the source code, but
l *vfs_unlink.cold+0x1d doesn't work.
How could I locate the source code for vfs_unlink.cold+0x1d/0x55?
