From: Steve French Date: Wed, 12 Oct 2011 22:47:03 +0000 (-0500) Subject: add new module parameter 'enable_oplocks' X-Git-Tag: v3.2-rc1~133^2~25 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e75047344ea415760b2508a6fa29c0288c7b6b68;p=pandora-kernel.git add new module parameter 'enable_oplocks' Thus spake Jeff Layton: "Making that a module parm would allow you to set that parameter at boot time without needing to add special startup scripts. IMO, all of the procfile "switches" under /proc/fs/cifs should be module parms instead." This patch doesn't alter the default behavior (Oplocks are enabled by default). To disable oplocks when loading the module, use modprobe cifs enable_oplocks=0 (any of '0' or 'n' or 'N' conventions can be used). To disable oplocks at runtime using the new interface, use echo 0 > /sys/module/cifs/parameters/enable_oplocks The older /proc/fs/cifs/OplockEnabled interface will be deprecated after two releases. A subsequent patch will add an warning message about this deprecation. Changes since v2: - make enable_oplocks a 'bool' Changes since v1: - eliminate the use of extra variable by renaming the old one to enable_oplocks and make it an 'int' type.
