+Subject: Remove low_latency flag setting from nozomi and mxser drivers
+X-Git-Tag: v2.6.31-rc1~16
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=4d8d4d251df8eaaa3dae71c8cfa7fbf4510d967d
+
 Remove low_latency flag setting from nozomi and mxser drivers
 
 The kernel oopses if this flag is set.
 
+[and neither driver should set it as they call tty_flip_buffer_push from IRQ
+ paths so have always been buggy]
