[PATCH v5 08/13] NFSD: Clean up nfsd4_init_file()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Name nfs4_file-related helpers consistently. There are already
nfs4_file_yada functions, so let's go with the same convention used
by put_nfs4_file(): init_nfs4_file().

Change the @fh parameter to be const pointer for better type safety.

Finally, move the hash insertion operation to the caller. This is
typical for most other "init_object" type helpers, and it is where
most of the other nfs4_file hash table operations are located.
