Subject: [PATCH] libparted: Flush parent device on open (#962611)
|
||
|
|
|
||
|
|
Parted probes for filesystems using geometry offsets into the parent
|
||
|
|
device, not the partition device itself. This means it may get stale
|
||
|
|
information if a partition has just been formatted.
|
||
|
|
|
||
|
|
On kernels before 2.6 this will also flush all partition devices. On 2.6
|
||
|
|
and newer kernels it will only flush the parent device.
|
||
|
|
|
||
|
|
* libparted/arch/linux.c (linux_open): Always call _flush_cache
