Subject: [PATCH] xfs_db: refactor timestamp printing
|
|
|
0bf83d |
|
|
|
0bf83d |
Introduce type-specific printing functions to xfs_db to print an
|
|
|
0bf83d |
xfs_timestamp instead of open-coding the timestamp decoding. This is
|
|
|
0bf83d |
needed to stay ahead of changes that we're going to make to
|
|
|
0bf83d |
xfs_timestamp_t in the following patches.
