Several existing dprink()/dfprintk() calls were converted to use the new
mount API logging macros by commit ce8866f0913f ("NFS: Attach
supplementary error information to fs_context"). If the fs_context was
not created using fsopen() then it will not have had a log buffer
allocated for it, and the new mount API logging macros will wind up
calling printk().
This can result in syslog messages being logged where previously there
were none... most notably "NFS4: Couldn't follow remote path", which can
happen if the client is auto-negotiating a protocol version with an NFS
server that doesn't support the higher v4.x versions.
Convert the nfs_errorf(), nfs_invalf(), and nfs_warnf() macros to check
for the existence of the fs_context's log buffer and call dprintk() if
it doesn't exist. Add nfs_ferrorf(), nfs_finvalf(), and nfs_warnf(),
which do the same thing but take an NFS debug flag as an argument and
call dfprintk(). Finally, modify the "NFS4: Couldn't follow remote
path" message to use nfs_ferrorf().
