Subject: [PATCH 43/52] inode: don't dump the whole table to CLI
|
|
|
14f8ab |
|
|
|
14f8ab |
dumping the whole inode table detail to screen doesn't solve any
|
|
|
14f8ab |
purpose. We should be getting only toplevel details on CLI, and
|
|
|
14f8ab |
then if one wants to debug further, then they need to get to
|
|
|
14f8ab |
'statedump' to get full details.
