Boaz Harrosh 6e31609b1d exofs: Remove useless optimization ... We used to compact all used devices in an IO to the beginning of the device array in an io_state. And keep a last device used so in later loops we don't iterate on all device slots. This does not prevent us from checking if slots are empty since in reads we only read from a single mirror and jump to the next mirror-set. This optimization is marginal, and needlessly complicates the code. Specially when we will later want to support raid/456 with same abstract code. So remove the distinction between "dev" and "comp". Only "dev" is used both as the device used and as the index (component) in the device array. [Note that now the io_state->dev member is redundant but I keep it because I might want to optimize by only IOing a single group, though keeping a group_width*mirrors devices in io_state, we now keep num-devices in each io_state] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>		15 years ago
