+Subject: btrfs: rename bitmap_set_bits() -> btrfs_bitmap_set_bits()
+
+From: Alexander Lobakin <aleksander.lobakin@intel.com>
+
+commit 4ca532d64648d4776d15512caed3efea05ca7195 upstream.
+
+bitmap_set_bits() does not start with the FS' prefix and may collide
+with a new generic helper one day. It operates with the FS-specific
+types, so there's no change those two could do the same thing.
+Just add the prefix to exclude such possible conflict.

+Subject: fs/ntfs3: add prefix to bitmap_size() and use BITS_TO_U64()
+
+From: Alexander Lobakin <aleksander.lobakin@intel.com>
+
+commit 3f5ef5109f6a054ce58b3bec7214ed76c9cc269f upstream.
+
+bitmap_size() is a pretty generic name and one may want to use it for
+a generic bitmap API function. At the same time, its logic is
+NTFS-specific, as it aligns to the sizeof(u64), not the sizeof(long)
+(although it uses ideologically right ALIGN() instead of division).
+Add the prefix 'ntfs3_' used for that FS (not just 'ntfs_' to not mix
+it with the legacy module) and use generic BITS_TO_U64() while at it.

+Subject: s390/cio: rename bitmap_size() -> idset_bitmap_size()
+
+From: Alexander Lobakin <aleksander.lobakin@intel.com>

+commit c1023f5634b9bfcbfff0dc200245309e3cde9b54 upstream.
+
+bitmap_size() is a pretty generic name and one may want to use it for
+a generic bitmap API function. At the same time, its logic is not
+"generic", i.e. it's not just `nbits -> size of bitmap in bytes`
+converter as it would be expected from its name.
+Add the prefix 'idset_' used throughout the file where the function
+resides.
