Subject: [PATCH 1/6] fuse: Change argument of fuse_flush_writepages()
Date: Tue, 06 Nov 2018 12:43:41 +0300 [thread overview]
Message-ID: <154149742122.18189.7228444587279544540.stgit@localhost.localdomain> (raw)
In-Reply-To: <154149673368.18189.14752124997476502777.stgit@localhost.localdomain>
Next patches introduce fuse_inode::lock, which will be used
in __releases() and __acquires() instead of fc->lock.
This patch makes this function to use argument fuse_inode
instead of inode as preparation for that.
