[PATCH] cifs: Do not use large smb buffers in response path
unless response is larger than 256 bytes. This cuts more than 1/3 of the large memory allocations that cifs does and should be a huge help to memory pressure under stress. Signed-off-by: Steve French (sfrench@us.ibm.com) Signed-off-by: Linus Torvalds <torvalds@osdl.org>
