commit c26b5aa8ef0d46035060fded475e6ab957b9f69f upstream.
GFS2 passes the inode buffer head (dibh) from gfs2_iomap_begin to gfs2_iomap_end in iomap->private. It sets that private pointer in gfs2_iomap_get. Users of gfs2_iomap_get other than gfs2_iomap_begin would have to release iomap->private, but this isn't done correctly, leading to a leak of buffer head references.
To fix this, move the code for setting iomap->private from gfs2_iomap_get to gfs2_iomap_begin.
Fixes: 64bc06bb32 ("gfs2: iomap buffered write support") Cc: stable@vger.kernel.org # v4.19
Now applied, thanks.
