Subject: lib/rbtree.c: fix typo in comment of __rb_insert()
X-Git-Tag: v3.17-rc1~73^2~111
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=1b9c53e849aa65776d4f611d99aa09f856518dad;p=linux.git

lib/rbtree.c: fix typo in comment of __rb_insert()

In case 1, it passes down the BLACK color from G to p and u, and maintains
the color of n.  By doing so, it maintains the black height of the
sub-tree.

While in the comment, it marks the color of n to BLACK.  This is a typo
and not consistents with the code.

This patch fixs this typo in comment.
