From: Ryusuke Konishi Date: Thu, 16 Apr 2015 19:46:25 +0000 (-0700) Subject: nilfs2: do not use async write flag for segment summary buffers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6fb7a61e98ac311a65bc652a12611d9899994f49;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git nilfs2: do not use async write flag for segment summary buffers The async write flag is introduced to nilfs2 in the commit 7f42ec394156 ("nilfs2: fix issue with race condition of competition between segments for dirty blocks"), but the flag only makes sense for data buffers and btree node buffers. It is not needed for segment summary buffers. This gets rid of the latter uses as part of refactoring of atomic bit operations on buffer state bitmap.
