Subject: ext3: kill 2 useless magic numbers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8ef2720397bb813d4985405a5ae7b8ad6474188b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ext3: kill 2 useless magic numbers

dx_root_limit() will never return 20, and I can't figure out what 20
stands for.  This function has never changed since htree directory
indexing was merged.

Similar for dx_node_limit() and the magic 22.
