Subject: [PATCH] nilfs2: remove redundant pointer sbufs
Pointer sbufs is being assigned a value but it's not being used
later on. The pointer is redundant and can be removed. Cleans up
scan-build static analysis warning:
fs/nilfs2/page.c:203:8: warning: Although the value stored to 'sbufs'
is used in the enclosing expression, the value is never actually read
from 'sbufs' [deadcode.DeadStores]
sbh = sbufs = page_buffers(src);
