I saw this compiler warning on my laptop: pgxn/neon_walredo/walredoproc.c:178:10: warning: using the result of an assignment as a condition without parentheses [-Wparentheses] if (err = close_range_syscall(3, ~0U, 0)) { ~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ pgxn/neon_walredo/walredoproc.c:178:10: note: place parentheses around the assignment to silence this warning if (err = close_range_syscall(3, ~0U, 0)) { ^ ( ) pgxn/neon_walredo/walredoproc.c:178:10: note: use '==' to turn this assignment into an equality comparison if (err = close_range_syscall(3, ~0U, 0)) { ^ == 1 warning generated. I'm not sure what compiler version or options cause that, but it's a good warning. Write the call a little differently, to avoid the warning and to make it a little more clear anyway. (The 'err' variable wasn't used for anything, so I'm surprised we were not seeing a compiler warning on the unused value, too.)

@problame now that we use Debian 12 on the pageservers, do we now have a version of glibc which wraps the close_range syscall? Seemingly this is the call to the wrapper you created months ago?
