> More recently, f2fs has started to support this feature as well, following the Ext4 implementation and framework, thanks to an effort led by Google. Most, if not all, of the information described here also applies to f2fs, with small changes on the commands used to configure the superblock. I'd guess that the f2fs changes at least are motivated by sdcard emulation on Android: sdcards were FAT32 in the beginning, so once they started being emulated with a backing store on the regular (ext4, then f2fs on pixels) data partition, case-insensitivity had to be emulated (first via a FUSE daemon in userspace, then via sdcardfs, a stackable FS in the kernel written by Samsung). (I work at Google on Android, but I don't have any first-hand knowledge about this.)
