Subject: [RFC] jffs2: work around unaligned accesses failing on bcm63xx/smp
|
|
|
|
|
|
|
|
|
|
Unligned memcpy_fromio randomly fails with an unaligned dst. Work around
|
|
|
|
|
it by ensuring we are always doing aligned copies.
|
|
|
|
|
|
|
|
|
|
Should fix filename corruption in jffs2 with SMP.
