Hi all,
in this thread ( https://lkml.org/lkml/2013/3/17/128 ), Al Viro argues that file_inode() is not equal to f_mapping->host in certain cases.
I'm asking, because in arch/x86/kernel/msr.c, msr_seek() retrieves the inode via f_mapping while one function later, msr_read() uses file_inode(). Is this on purpose?
In general, how do I distinguish when to use what?
Thanks in advance, Andre
