From 1267df40acb2da62b1641abae26132411d093fb3 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Sat, 4 May 2024 12:29:46 -0400 Subject: [PATCH] bcachefs: Initialize bch_write_op->failed in inline data path Normally this is initialized in __bch2_write(), which is executed in a loop, but the inline data path skips this.
