Re: [PATCH v5 00/27] nfs: Mount API conversion

[Scott Mayhew]

Hi Anna, Trond,

Have you had a chance to look at these?  Do you have any comments?  I do
have a small fix to make to nfs4_validate_fspath() for an issue that Dan
Carpenter reported, but I was waiting to see if there was anything else.
