From fffe9bee14b0e04ef632b96279fa44cb3df80812 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Fri, 30 Jul 2021 13:23:49 -0500 Subject: [PATCH] gfs2: Delay withdraw from atomic context Before this patch, if function __gfs2_ail_flush detected an error syncing the ail list, it call gfs2_ail_error which called gfs2_withdraw. Since __gfs2_ail_flush deals with a specific glock, we shouldn't withdraw immediately because the withdraw code (signal_our_withdraw) uses glocks in its processing. This patch changes the call from gfs2_withdraw to gfs2_withdraw_delayed which defers the withdraw until a more appropriate context, such as the logd daemon, discovers the intent to withdraw.
