A limitation of the fstrim patch is that it didn't work for partitions. This is because of the convoluted way that we were searching for the /sys/block device using directory searching.
A simpler way to do it is to go via /sys/dev/block/MAJOR:MINOR and this also lets us easily map from partitions to devices, to find the discard parameters of the parent device. This commit removes all the complex directory searching, and just uses simple file opens. It also ensures that the partition is aligned to the discard block size. In older Windows (before ~2008) partitions were aligned to 512 bytes. The discard block size is usually 4K or larger. Therefore it's (nearly) impossible to discard correctly on these partitions. This patch rejects these cases. Rich. ------------------------------------------------------------------------------ Infragistics Professional Build stunning WinForms apps today!
