Subject: [PATCH next 1/2] btrfs: tree-checker: Fix error format string
Date: Fri,  8 Nov 2019 22:38:52 +0100	[thread overview]
Message-ID: <20191108213853.16635-2-afaerber@suse.de> (raw)
In-Reply-To: <20191108213853.16635-1-afaerber@suse.de>

From: Andreas Färber <afaerber@suse.com>

Argument BTRFS_FILE_EXTENT_INLINE_DATA_START is defined as offsetof(),
which returns type size_t, so we need %zu instead of %lu.

This fixes a build warning on 32-bit arm:

  ../fs/btrfs/tree-checker.c: In function 'check_extent_data_item':
  ../fs/btrfs/tree-checker.c:230:43: warning: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Wformat=]
    230 |     "invalid item size, have %u expect [%lu, %u)",
        |                                         ~~^
        |                                           |
        |                                           long unsigned int
        |                                         %u
