Why are you omitting the part immediately leading your quote? --- Arranges for the drive to be safely removed and powered off. On the OS side this includes ensuring that no process is using the drive, then requesting that in-flight buffers and caches are committed to stable storage. The exact steps for powering off the drive depends on the drive itself and the interconnect used. --- It is not the job of solid to reinvent proper device handling, but communicate with the operating system and its helpers. If the power down sequence is not implemented properly in UDisks2, it would be a bug in UDisks2, or possibly in the kernel. -- You are receiving this mail because: You are watching all bug changes.
