You have x (exec) permission, which is required to enter a directory, but no r permission
That's why you could cd' into this dir but was not able to list its contents

Hey everyone, I really love this project and I believe it is one of the best ways for us as a community to keep a up-to-date book about how some of the internals work, besides to the real specific documentation of the kernel itself. I hope that we can further maintain this book and make it up-to-date. I'm currently working on the interrupts chapter. I would really appreciate any reviews of the pull request I created.
@MusaSakizci I'm interested in network-subsystem. So we can collaborate for that topic as an academic research. Thanks for your contribution.
@hwpplayer1 I guess you have already spotted this, but there was some attempt started 3 years ago https://github.com/ayyucedemirbas/linux-insides_Turkish . Maybe you can use that.
@tylkosimon Hey, yeah a few people are here. Welcome to linux-insides!
Hi @Nsamdarshi_twitter, we will need a little bit more information, like Is this happening in userspace (for example: are you running a browser and in freezes during execution), if it is happening in userspace does it happen for different applications? Which distribution do you run? Which kernel version? What kind of hardware? Did you take a look at
sudo dmesg? Or at sudo journalctl? Is your laptop (if it is a laptop) hot at the point of the freeze? When did the freezing start, think about any specific actions, that happend before. If these started very recently you can observe your actions with the history command (which can show the date of the action after appending HISTTIMEFORMAT="%d/%m/%y %T " to your ~/.bashrc file and executing source ~/.bashrc afterwards.
As you can see there are plenty of reasons why this could happen and nobody here has magic abilities or is a fortune teller. Please always provide as much information as you possibly can when asking for technical advice. Otherwise, people can get the idea that you have no respect for their time.
@hwpplayer1 Good to hear, thanks for any help. I don't have to much time currently as I currently work on http://web.archive.org/web/20190419223312/https://www.ops-class.org/asst/1/
./drivers/md/bcache/request.c:675: part_round_stats(cpu, &s->d->disk->part0);
as you see, in the file
request.c, only two parameters are passed to the function part_round_stats, but this function is declared that three parameters are necessary.
./include/linux/genhd.h:408:extern void part_round_stats(struct request_queue q, int cpu, struct hd_struct part);
My system is CentOS 7 and I got the source code from here: wget "http://vault.centos.org/7.6.1810/os/Source/SPackages/kernel-3.10.0-957.el7.src.rpm"
I kind of can't believe that there is such a fatal error in the source of kernel. Does anyone know why I got this issue?
anyone interested in linux tracing? I did write a sort of a tutorial: https://github.com/Stefan20162016/tracing . Comments are welcome.
