Uh, yes, sorry; I'm not sure how I let that slip, I guess I didn't hit any dead lock because nothing ever tried to take a write lock after getdents... Thanks! I expect there'll be other comments (this might not make it at all), so I'll keep the v3 of this patch with this fix locally and resend after other comments. > a551138c4b3b9f Dominique Martinet 2023-05-10 1853 if (ctx->flags & DIR_CONTEXT_F_NOWAIT) { > a551138c4b3b9f Dominique Martinet 2023-05-10 1854 if (!down_read_trylock(&root->kernfs_rwsem)) > a551138c4b3b9f Dominique Martinet 2023-05-10 1855 return 0; > > It's a bit strange the this doesn't return -EAGAIN; That is on purpose: the getdents did work (dir_emit returned success at least once), so the caller can process whatever was filled in the buffer before calling iterate_shared() again. If we were to return -EAGAIN here, we'd actually be throwing out the entries we just filled in, and that's not what we want.
