Subject: [PATCH 28/30] tests: add a helper to check the kernel knows about a
|
||
|
|
file system
|
||
|
|
|
||
|
|
Some tests need both the file system tools (eg mkfs.vfat) and kernel
|
||
|
|
support (eg vfat kernel module) to pass.
|
||
|
|
|
||
|
|
There are already helpers such as require_fat_ which check for mkfs.vfat,
|
||
|
|
but if the kernel doesn't support the filesystem then mounting the disk
|
||
|
|
image will fail.
|
||
|
|
|
||
|
|
Add require_filesystem_, which checks for either the filesystem name in
|
||
|
|
/proc/filesystems (so it's built-in, or already loaded) or if the name
|
||
|
|
is a valid module (so can be loaded on demand).

||
