Vyacheslav Dubeyko bd2c003532 hfsplus: fix remount issue ... Current implementation of HFS+ driver has small issue with remount option. Namely, for example, you are unable to remount from RO mode into RW mode by means of command "mount -o remount,rw /dev/loop0 /mnt/hfsplus". Trying to execute sequence of commands results in an error message: mount /dev/loop0 /mnt/hfsplus mount -o remount,ro /dev/loop0 /mnt/hfsplus mount -o remount,rw /dev/loop0 /mnt/hfsplus mount: you must specify the filesystem type mount -t hfsplus -o remount,rw /dev/loop0 /mnt/hfsplus mount: /mnt/hfsplus not mounted or bad option The reason of such issue is failure of mount syscall: mount("/dev/loop0", "/mnt/hfsplus", 0x2282a60, MS_MGC_VAL|MS_REMOUNT, NULL) = -1 EINVAL (Invalid argument) Namely, hfsplus_parse_options_remount() method receives empty "input" argument and return false in such case. As a result, hfsplus_remount() returns -EINVAL error code. This patch fixes the issue by means of return true for the case of empty "input" argument in hfsplus_parse_options_remount() method.
