This patch adds support for exposing DIF protection device attributes via configfs. This includes: pi_prot_type: Protection Type (0, 1, 3 currently support) pi_prot_format: Protection Format Operation (FILEIO only) Within se_dev_set_pi_prot_type() it also adds the se_subsystem_api device callbacks to setup per device protection information. v2 changes: - Drop pi_guard_type + pi_prot_version related code (MKP) - Add pi_prot_format logic (Sagi) - Add ->free_prot callback in target_free_device - Add hw_pi_prot_type read-only attribute Cc: Martin K.

This patch adds support for DIF read/write verify emulation for TARGET_DIF_TYPE1_PROT + TARGET_DIF_TYPE3_PROT operation. This includes sbc_dif_verify_write() + sbc_dif_verify_read() calls accessable by backend drivers to perform DIF verify for SGL based data and protection information. Also included is sbc_dif_copy_prot() logic to copy protection information to/from backend provided protection SGLs. Based on scsi_debug.c DIF TYPE1+TYPE3 emulation. v2 changes: - Select CRC_T10DIF for TARGET_CORE in Kconfig (Fengguang) - Drop IP checksum logic from sbc_dif_v1_verify (MKP) - Fix offset on app_tag = 0xffff in sbc_dif_verify_read() Cc: Martin K.

Also, add calls in sbc_parse_cdb() for READ_[10,12,16] + WRITE_[10,12,16] to perform DIF sanity checking. v2 changes: - Make sbc_check_prot defined as static (Fengguang + Wei) - Remove unprotected READ/WRITE warning (mkp) - Populate cmd->prot_type + friends (Sagi) - Drop SCF_PROT usage Cc: Martin K.

Also included is struct se_dif_v1_tuple, along with changes to struct se_cmd, struct se_dev_attrib, and struct se_device. Also, add new se_subsystem_api->[init,format,free]_prot() callers used by target core code to setup backend specific protection information after the device has been configured.

Merge tag 'trace-fixes-3.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "A regression showed up that there's a large delay when enabling all events. This was prevalent when FTRACE_SELFTEST was enabled which enables all events several times, and caused the system bootup to pause for over a minute. This was tracked down to an addition of a synchronize_sched() performed when system call tracepoints are unregistered. The synchronize_sched() is needed between the unregistering of the system call tracepoint and a deletion of a tracing instance buffer. But placing the synchronize_sched() in the unreg of *every* system call tracepoint is a bit overboard. A single synchronize_sched() before the deletion of the instance is sufficient" * tag 'trace-fixes-3.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Only run synchronize_sched() at instance deletion time
