For example:\n\n thread1: going through a big range, stops in the middle of a vma and\n stores the restart address in vm_truncate_count.\n\n thread2: comes in with a small (e.g. single page) unmap request on\n the same vma, somewhere before restart_address, finds that the\n vma was already unmapped up to the restart address and happily\n returns without doing anything.\n\nAnother scenario would be two big unmap requests, both having to\nrestart the unmapping and each one setting vm_truncate_count to its\nown value. This could go on forever without any of them being able to\nfinish.\n\nTruncate and hole punching already serialize with i_mutex. Other\ncallers of unmap_mapping_range() do not, and it\u0027s difficult to get\ni_mutex protection for all callers.

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
