Message-Id: <20240123152520.4294-4-jack@suse.cz> Date: Tue, 23 Jan 2024 16:25:03 +0100 From: Jan Kara <jack@...e.cz> To: <linux-fsdevel@...r.kernel.org> Cc: <linux-ext4@...r.kernel.org>, Matthew Wilcox <willy@...radead.org>, Jan Kara <jack@...e.cz> Subject: [PATCH 4/9] udf: Remove GFP_NOFS allocation in udf_expand_file_adinicb() udf_expand_file_adinicb() is called under inode->i_rwsem and mapping->invalidate_lock. i_rwsem is safe wrt fs reclaim, invalidate_lock on this inode is safe as well (we hold inode reference so reclaim will not touch it, furthermore even lockdep should not complain as invalidate_lock is acquired from udf_evict_inode() only when truncating inode which should not happen from fs reclaim).
