From e19089dff547c9e1f09712acc3536d7b0aa9ce3d Mon Sep 17 00:00:00 2001 From: Baokun Li Date: Tue, 19 Mar 2024 19:33:25 +0800 Subject: [PATCH] ext4: clean up s_mb_rb_lock to fix build warnings with C=1 Running sparse (make C=1) on mballoc.c we get the following warning: fs/ext4/mballoc.c:3194:13: warning: context imbalance in 'ext4_mb_seq_structs_summary_start' - wrong count at exit This is because __acquires(&EXT4_SB(sb)->s_mb_rb_lock) was called in ext4_mb_seq_structs_summary_start(), but s_mb_rb_lock was removed in commit 83e80a6e3543 ("ext4: use buckets for cr 1 block scan instead of rbtree"), so remove the __acquires to silence the warning.
