lib: update single-char callers of strtobool()

2016-10-28T07:01:30Z

commit 1404297ebf76fd91a41de215fc8c94c2619e5fdb upstream. Some callers of strtobool() were passing a pointer to unterminated strings. In preparation of adding multi-character processing to kstrtobool(), update the callers to not pass single-character pointers, and switch to using the new kstrtobool_from_user() helper where possible.

cifs: Ratelimit kernel log messages

2016-02-25T20:01:17Z

commit ec7147a99e33a9e4abad6fc6e1b40d15df045d53 upstream. Under some conditions, CIFS can repeatedly call the cifs_dbg() logging wrapper. If done rapidly enough, the console framebuffer can softlockup or "rcu_sched self-detected stall". Apply the built-in log ratelimiters to prevent such hangs.

cifs: convert printk(LEVEL...) to pr_

2014-12-08T04:48:07Z

The useful macros embed message level in the name. Thus, it cleans up the code a bit. In cases when it was plain printk() the conversion was done to info level. Signed-off-by: Andy Shevchenko Signed-off-by: Steve French

[CIFS] cifs: Rename cERROR and cFYI to cifs_dbg

2013-05-05T03:17:23Z

It's not obvious from reading the macro names that these macros are for debugging. Convert the names to a single more typical kernel style cifs_dbg macro. cERROR(1, ...) -> cifs_dbg(VFS, ...) cFYI(1, ...) -> cifs_dbg(FYI, ...) cFYI(DBG2, ...) -> cifs_dbg(NOISY, ...) Move the terminating format newline from the macro to the call site. Add CONFIG_CIFS_DEBUG function cifs_vfs_err to emit the "CIFS VFS: " prefix for VFS messages. Size is reduced ~ 1% when CONFIG_CIFS_DEBUG is set (default y) $ size fs/cifs/cifs.ko* text data bss dec hex filename 265245 2525 132 267902 4167e fs/cifs/cifs.ko.new 268359 2525 132 271016 422a8 fs/cifs/cifs.ko.old Other miscellaneous changes around these conversions: o Miscellaneous typo fixes o Add terminating \n's to almost all formats and remove them from the macros to be more kernel style like. A few formats previously had defective \n's o Remove unnecessary OOM messages as kmalloc() calls dump_stack o Coalesce formats to make grep easier, added missing spaces when coalescing formats o Use %s, __func__ instead of embedded function name o Removed unnecessary "cifs: " prefixes o Convert kzalloc with multiply to kcalloc o Remove unused cifswarn macro Signed-off-by: Joe Perches Signed-off-by: Jeff Layton Signed-off-by: Steve French

cifs: Add CONFIG_CIFS_DEBUG and rename use of CIFS_DEBUG
