Subject: Tools: hv: vssdaemon: skip all filesystems mounted readonly
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9e5db05aae4657c7ade34ccc4b93f27ab647498e;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Tools: hv: vssdaemon: skip all filesystems mounted readonly

Instead of making a list of exceptions for readonly filesystems
in addition to iso9660 we already have it is better to skip freeze
operation for all readonly-mounted filesystems.
