[PATCH v2 005/144] KVM: selftests: Always open VM file descriptors with O_RDWR

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Drop the @perm param from vm_create() and always open VM file descriptors
with O_RDWR.  There's no legitimate use case for other permissions, and
if a selftest wants to do oddball negative testing it can open code the
necessary bits instead of forcing a bunch of tests to provide useless
information.
