Hi Linus, Miklos, Ira, It seems that two patches that got merged in the 5.8 merge window collided and no one noticed until now: 80340fe3605c0 (Miklos Szeredi 2020-05-14 184) #define STATX_ATTR_MOUNT_ROOT 0x00002000 /* Root of a mount */ ... 712b2698e4c02 (Ira Weiny 2020-04-30 186) #define STATX_ATTR_DAX 0x00002000 /* [I] File is DAX */ The question is, what do we do about it? Renumber one or both of the constants? David
