Subject: [PATCH] fuse: remove clear_page_dirty() call
X-Git-Tag: v2.6.20-rc2~68
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9280f6822c2d7112b47107251fce307aefb31f35;p=linux-2.6

[PATCH] fuse: remove clear_page_dirty() call

The use by FUSE was just a remnant of an optimization from the time
when writable mappings were supported.

Now FUSE never actually allows the creation of dirty pages, so this
invocation of clear_page_dirty() is effectively a no-op.
