It would have moved on\nto SUSPEND_ACKTO but never been able to reach SUSPEND_DONE.\n\nSo change the loop to only run while SUSPEND_ACKED rather than until\nSUSPEND_DONE.

      "message": "llseek: automatically add .llseek fop\n\nAll file_operations should get a .llseek operation so we can make\nnonseekable_open the default for future file operations without a\n.llseek pointer.\n\nThe three cases that we can automatically detect are no_llseek, seq_lseek\nand default_llseek. For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.  Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a semantic\npatch that does all this.\n\n\u003d\u003d\u003d\u003d\u003d begin semantic patch \u003d\u003d\u003d\u003d\u003d\n// This adds an llseek\u003d method to all file operations,\n// as a

      "message": "Freezer: make kernel threads nonfreezable by default\n\nCurrently, the freezer treats all tasks as freezable, except for the kernel\nthreads that explicitly set the PF_NOFREEZE flag for themselves.  This\napproach is problematic, since it requires every kernel thread to either\nset PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn\u0027t\ncare for the freezing of tasks at all.\n\nIt seems better to only require the kernel threads that want to or need to\nbe frozen to use some freezer-related code and to remove any\nfreezer-related code from the other (nonfreezable) kernel threads, which is\ndone in this patch.\n\nThe patch causes all kernel threads to be nonfreezable by default (ie.  to\nhave PF_NOFREEZE set by default) and introduces the set_freezable()\nfunction that should be called by the freezable kernel threads in order to\nunset PF_NOFREEZE.  It also makes all of the currently freezable kernel\nthreads call set_freezable(), so it shouldn\u0027t cause any (intentional)\nchange of behaviour to appear.  Additionally, it updates documentation to\ndescribe the freezing of tasks more accurately.\n\n[akpm@linux-foundation.org: build fixes]\nSigned-off-by: Rafael J.
