Hi, Doesn't it consider SD path? It have a problem with uninitialized 'context_info'. 'context_info' is moved into mmc_host struct in v4. Please, could you explain the reason in brief? Thanks, Seungwon Jeon On Wednesday, December 05, 2012, Konstantin Dorfman wrote: > When current request is runn

[PATCH v4] mmc: fix async request mechanism for sequential read scenarios

2012-12-05 Thread Konstantin Dorfman
When current request is running on the bus and if next request fetched by mmcqd is NULL, mmc context (mmcqd thread) gets blocked until the current request completes. This means if new request comes in while the mmcqd thread is blocked, this new request can not be prepared in parallel to current ong
