Subject: tools: hv: skip iso9660 mounts in hv_vss_daemon
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=10b637b4c8a21b299f691cecc4b6f16f44936c6d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

tools: hv: skip iso9660 mounts in hv_vss_daemon

fsreeze does not work for iso9660 filesystems. A ENOSUPP may be caught
in the freeze case, but the subsequent thaw call would fail and leads to
a false error.
