Subject: parted: Make informing the kernel more reliable
|
|
References: bnc#657360
|
|
Patch-mainline: no
|
|
|
|
This patch should make parted's process of informing the kernel
|
|
about changes of partition table sligtly more reliable.
|
|
It consists of 2 quite unrelated parts:
|
|
|
|
* increase the max sleep time if partition is busy from 1 to 2 seconds
|
|
* do not inform the kernel when only partition flags change - kernel
|
|
does not care about the flags
|
