Subject: exofs: stop using s_dirt
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=66153f6e0f89c75d18e490739b0149dfd2e53b69;p=linux-beck.git

exofs: stop using s_dirt

Exofs has the '->write_super()' handler and makes some use of the '->s_dirt'
superblock flag, but it really needs neither of them because it never sets
's_dirt' to one which means the VFS never calls its '->write_super()' handler.
Thus, remove both.

Note, I am trying to remove both 's_dirt' and 'write_super()' from VFS
altogether once all users are gone.
