IB/iser: Add missing counter increment in iser_data_buf_aligned_len()

2007-11-24T21:50:39Z

While adding sg chaining support to iSER, a "for" loop was replaced with a "for_each_sg" loop. The "for" loop included the incrementation of 2 variables. Only one of them is incremented in the current "for_each_sg" loop. This caused iSER to think that all data is unaligned, and all data was copied to aligned buffers. This patch increments the missing counter inside the "for_each_sg" loop whenever necessary. Signed-off-by: Erez Zilber Signed-off-by: Roland Dreier

IB/iser: Make a couple of functions static

2007-07-18T01:37:42Z

Make iser_conn_release() and iser_start_rdma_unaligned_sg() static, since they are only used in the .c file where they are defined. In addition to being a cleanup, this even shrinks the generated code by allowing the single call of iser_start_rdma_unaligned_sg() to be inlined into its callsite.

IB/iser: Remove unused "write-only" variables

2006-12-12T19:50:20Z

Remove variables that are set but then never looked at in the iSER initiator. These cleanups came from David Binderman's list of "set but never used" warnings from icc. Signed-off-by: Roland Dreier

[PATCH] LOG2: Implement a general integer log2 facility in the kernel

2006-12-08T16:28:51Z

This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

IB/iser: DMA unmap unaligned for RDMA data before touching it

2006-09-28T17:53:18Z

iSER uses the DMA mapping api to map the page holding the SCSI command data to the HCA DMA address space. When the command data is not aligned for RDMA, the data is copied to/from an allocated buffer which in turn is used for executing this command. The pages associated with the command must be unmapped before being touched. Signed-off-by: Erez Zilber Signed-off-by: Roland Dreier
