6 years agoscsi: storvsc: use in place iterator function
Stephen Hemminger [Thu, 18 May 2017 16:18:11 +0000 (09:18 -0700)]
scsi: storvsc: use in place iterator function

In 4.12-rc1, new functions were added to support iterating over elements
in the vmbus event ring. This patch uses them to simplify the ring
buffer handling in virtual SCSI driver as well.

iscsiadm: Could not login to [iface: default, target: iqn.1986-03.com...

compiler, clang: properly override 'inline' for clang

Commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused
static inline functions") just caused more warnings due to re-defining
the 'inline' macro.

So undef it before re-defining it, and also add the 'notrace' attribute
like the gcc version that this is overriding does.

Maybe this makes clang happier.

excessive checks in ufs_write_failed() and ufs_evict_inode()

As it is, short copy in write() to append-only file will fail
to truncate the excessive allocated blocks.  As the matter of
fact, all checks in ufs_truncate_blocks() are either redundant
