[PATCH 12/13] fusectl: don't ignore options

From: Miklos Szeredi
Date: Wed Jun 19 2019 - 08:35:58 EST


The options "sync", "async", "dirsync", "lazytime", "nolazytime", "mand"
and "nomand" make no sense for the fusectl filesystem. If these options
are supplied to fsconfig(FSCONFIG_SET_FLAG), then return -EINVAL instead of
silently ignoring the option.

Any implementation, such as mount(8) that needs to parse this option
without failing should simply ignore the return value from fsconfig().
