Subject: [PATCH] Various suser() -> capable() chang
Date: 26 Apr 2002 19:28:28 -0400 [thread overview]
Message-ID: <1019863708.8034.3092.camel@neptune> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 1491 bytes --]
Hello,
I've made several cleanups changeing suser() to capable(CAP_SYS_ADMIN)
changes. This patch is mostly one line changes to 20 files, some files
with more. If any maintainers want to pick up these changes and
integrate them themselves, it would be appreciated. I can easily split
the patch if needed. This patch is aginst 2.5.10, and is already in
2.5.9-dj1.
DaveJ: same patch, just re-diffed.
Colin
