Subject: libext2fs: properly free the bitmaps in read_bitmap()'s error/cleanup path
X-Git-Tag: v1.45.5~46
X-Git-Url: https://git.whamcloud.com/gitweb?a=commitdiff_plain;h=a2a8cec68c69583b8de5409ade3cd641c7d4cef7;p=tools%2Fe2fsprogs.git

libext2fs: properly free the bitmaps in read_bitmap()'s error/cleanup path

Use ext2fs_free_{block,inode}_bitmaps() instead of ext2fs_free_mem()
to avoid some memory leaks if there is an error while calling
read_bitmaps().
