Subject: Get rid of CONFIG_LSF
|

X-Git-Tag: v2.6.29-rc1~569^2~7

X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=b3a6ffe16b5cc48abe7db8d04882dc45280eb693

Get rid of CONFIG_LSF
|
||||
|
||||
We have two seperate config entries for large devices/files. One
|
||||
is CONFIG_LBD that guards just the devices, the other is CONFIG_LSF
|
||||
that handles large files. This doesn't make a lot of sense, you typically
|
||||
want both or none. So get rid of CONFIG_LSF and change CONFIG_LBD wording
|
||||
to indicate that it covers both.
