Subject: [PATCH 0/1] docs/vfs: update references to i_mutex to i_rwsem

Hi!

I'm trying to update the VFS documentation and docstrings about the
non-existent i_mutex. Not sure if the distinction between shared and exclusive
usage of i_rwsem is clear and correct across all the changes though.

For instance, does __d_move expect the two i_rwsem to be held exclusively? It
seems to me __d_unalias only uses inode_trylock_shared on the first argument to
__d_move.

Thanks,
Junxuan
