md: fix return value of rdev_size_change() (c26a44ed) · Commits · 戴 / test

When trying to grow an array by enlarging component devices, rdev_size_store() expects the return value of rdev_size_change() to be in sectors, but the actual value is returned in KBs. This functionality was broken by commit so this patch is suitable for any kernel since 2.6.30. Cc: stable@kernel.org Signed-off-by:
