[PATCH v1 10/12] nfsd: Avoid non-flexible API in seq_quote_mem()

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

 



string_escape_mem_ascii() followed by seq_escape_mem_ascii() is completely
non-flexible and shouldn't be exist from day 1.

Replace it with properly called string_escape_mem().
