All of the cases where I added that were already\nmarked as deprecated or obsolete somewhere in the manual page,\nso this is just about uniformity and visual effect rather than\na new deprecation notice.\n\nThere are cases where the syscalls have been simply removed, and\nso they are obviously not to be used any more.\n\nThere are cases where some implementation (not necessarily Linux)\nis dangerous.\n\nIn some other cases, the functions have been obsoleted by POSIX,\nbut are still there in Linux without any deprecation notices.\nIn these cases, if there's no clear replacement, or if the\nreplacement is not a straight drop-in, or if the replacement adds\nmore complexity, I didn't add the [[deprecated]] attribute.\n\nA list of the system calls that I skipped in this patch set:\n\n- utime(2)\n\tMany filesystems have 1 second resolution, so it makes\n\tsense to use it in those cases. git(1) for example uses\n\tutime(2) consistently. Although deprecated by POSIX, it\n\tis still part of POSIX; if it ever removes it, we can\n\treconsider.\n\n- setpgrp(2) (the POSIX/SysV version)\n\tPOSIX deprecated it (not yet removed), but the manual page\n\tdoesn't mention any replacement.\n\nCheers,\n\nAlex\n\n\n---\n\nAlejandro Colomar (22):\n bdflush.2: SYNOPSIS: Mark as [[deprecated]]\n create_module.2: SYNOPSIS: Mark as
