bcachefs: thread_with_stdio: fix spinning instead of exiting

2025-05-04T18:00:14Z

bch2_stdio_redirect_vprintf() was missing a check for stdio->done, i.e. exiting. This caused the thread attempting to print to spin, and since it was being called from the kthread ran by thread_with_stdio, the userspace side hung as well. Change it to return -EPIPE - i.e. writing to a pipe that's been closed. Reported-by: Jan Solanti Signed-off-by: Kent Overstreet

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43Z

no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

bcachefs: twf: convert bch2_stdio_redirect_readline() to darray

2024-07-14T23:00:14Z

We now read the line from the buffer atomically, which means we have to allow the buffer to grow past STDIO_REDIRECT_BUFSIZE if we're waiting for a full line - this behaviour is necessary for stdio_redirect_readline_timeout() in the next patch. Signed-off-by: Kent Overstreet

2024-04-16T23:11:49Z
