Is FIEMAP supported on a DoM file? I have a simple file that is a 2
component PFL. The first component is DoM. My utility program that
does the FIEMAP, and which works with non-DoM PFL files, does not work
when the first component is DoM.
ioctl(FS_IOC_FIEMAP) fe_device=0 fe_logical=0 file_size=1048576000 error
Unknown error 524
Is this as expected?
