Bcache only does recoverable I/O for read operations by calling cached_dev_read_error(). For write opertions there is no I/O recovery for failed requests. But in bch_count_io_errors() no matter read or write I/Os, before errors counter reaches io error limit, pr_err() always prints "IO error on %, recoverying". For write requests this information is misleading, because there is no I/O recovery at all. This patch adds a parameter 'is_read' to bch_count_io_errors(), and only prints "recovering" by pr_err() when the bio direction is READ.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
