Subject: [PATCH 269/276] ec: fix truncate lock to cover the write in tuncate
|
|
|
17b94a |
clean
|
|
|
17b94a |
|
|
|
17b94a |
ec_truncate_clean does writing under the lock granted for truncate,
|
|
|
17b94a |
but the lock is calculated by ec_adjust_offset_up, so that,
|
|
|
17b94a |
the write in ec_truncate_clean is out of lock.
