Always push the metadata update to the worker thread upon completion of the data write. This fixes a deadlock caused by an IO completion thread blocking on a write. Thanks to Feng Yu for finding, reporting the bug and Jens Axboe for the fix.	Mohan Srinivasan	More...				over 15 years ago

Remove the calls to unplug the ssd's device queue after enqueueing an IO to it. This was done a long time ago to optimize for a perverse workload, but it breaks almost all common workloads by inhibiting request merging. This change reduces ssd %util significantly and has other beneficial effects.	Mohan Srinivasan	More...				almost 16 years ago

Changes to cut down the memory footprint of flashcache by 1/3 by cutting down the per-block in-memory metadata by 1/3. This results in big savings. For a 600GB cache this cuts down the memory footprint by 1.2GB, for a 300GB cache, the savings is 600MB.	Mohan Srinivasan	More...				about 16 years ago

Replace kmap() with kmap_atomic in the block checksum path, since kmap can block and checksum computes can be done from softirq. This fixes a panic where kmap() blocks when checksum validation is done from softirq.	Mohan Srinivasan	More...				about 16 years ago
