Analyze and fix the following issue in the Linux kernel code: md/raid1: allow fix_read_error to read from recovering device.
Problem Details: When attempting to fix a read error, it is acceptable to read from a device that is recovering, provided the recovery has got past the place we are reading from. This makes the test for "can we read from here" the same as the test in read_balance. Signed-off-by: majianpeng <majianpeng@gmail.com> Sign...
