fh_verify - filehandle lookup and access checking : pointer to current rpc request : filehandle to be verified : expected type of object pointed to by filehandle : type of access needed to object

Look up a dentry from the on-the-wire filehandle, check the client's access to the export, and set the current task's credentials.

Regardless of success or failure of fh_verify(), fh_put() should be called on when the caller is finished with the filehandle.

fh_verify() may be called multiple times on a given filehandle, for example, when processing an NFSv4 compound. The first call will look up a dentry using the on-the-wire filehandle. Subsequent calls will skip the lookup and just perform the other checks and possibly change the current task's credentials.

specifies the type of object expected using one of the S_IF* constants defined in include/linux/stat.h. The caller may use zero to indicate that it doesn't care, or a negative integer to indicate that it expects something not of the given type.

is formed from the NFSD_MAY_* constants defined in include/linux/nfsd/nfsd.h.
