Subject: [f2fs-dev] [PATCH] f2fs: fix to initialize map.m_pblk in f2fs_precache_extents()
Date: Sat, 7 Oct 2023 15:45:52 +0800 [thread overview]
Message-ID: <20231007074552.3170496-1-chao@kernel.org> (raw)
Otherwise, it may print random physical block address in tracepoint
of f2fs_map_blocks() as below:
f2fs_map_blocks: dev = (253,16), ino = 2297, file offset = 0, start blkaddr = 0xa356c421, len = 0x0, flags = 0
Fixes: c4020b2da4c9 ("f2fs: support F2FS_IOC_PRECACHE_EXTENTS")
