+Subject: udf: Fix bitmap overflow on large filesystems with small block size
+
+From: Jan Kara <jack@suse.cz>
+
+commit 89b1f39eb4189de745fae554b0d614d87c8d5c63 upstream.
+
+For large UDF filesystems with 512-byte blocks the number of necessary
+bitmap blocks is larger than 2^16 so s_nr_groups in udf_bitmap overflows
+(the number will overflow for filesystems larger than 128 GB with
+512-byte blocks). That results in ENOSPC errors despite the filesystem
+has plenty of free space.
+
+Fix the problem by changing s_nr_groups' type to 'int'. That is enough
+even for filesystems 2^32 blocks (UDF maximum) and 512-byte blocksize.
