X-Git-Tag: v3.12-rc1~26378^2~10 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=85becc535b7f33be5aefdb8ecea9fac4998e4b6f;p=kernel%2Fkernel-generic.git [JFFS2] Relax threshold for triggering GC due to dirty blocks. Instead of matching resv_blocks_gcmerge, which is only about 3, instead match resv_blocks_gctrigger, which includes a proportion of the total device size. These ought to become tunable from userspace, at some point.
