Message-Id: <20171009150042.31293-1-jack@suse.cz> Date: Mon, 9 Oct 2017 17:00:40 +0200 From: Jan Kara <jack@...e.cz> To: <linux-ext4@...r.kernel.org> Cc: Al Viro <viro@...IV.linux.org.uk>, Jia-Ju Bai <baijiaju1990@....com>, Linus Torvalds <torvalds@...ux-foundation.org>, Jan Kara <jack@...e.cz> Subject: [PATCH 0/2] ext2: Avoid parsing options under a spinlock Hello, as Jia-Ju Bai pointed out, match_int() can sleep due to GFP_KERNEL allocation. Change ext2 mount option parsing so that it does not happen under sbi->s_lock spinlock. That is a reasonable change anyway and as a sideeffect we don't have to restore old options if new options cannot be used for some reason. If nobody objects, I'll push these patches through my tree.
