Hi all, I was going through the VFS layer recently as part of learning how NuttX handles file permissions bits and while reading through proxy_fstat() in fs_fstat.c. I noticed a small what looks like a small typo. In the block driver proxy path, the write permissions bits are gated on ->read instead of ->write:
Around line 120 of fs_fstat() [image: image.png] Because of this, a driver implementing read but not write would incorrectly have its write bits set in the fstat() result. If there’s a reason for checking ->read here, I’d like to understand it. If it is a typo, I can send a small fix. Happy to be wrong and learn :) Thanks, Abhishek
