Subject: Re: [Bug #12210] 2.6.28-rc8 big regression in VM
Date: Thu, 26 Feb 2009 19:06:36 +0100 [thread overview]
Message-ID: <20090226180636.GE4374@ics.muni.cz> (raw)
In-Reply-To: <20081225112017.GB16080@localhost>
Hello,
you may remember that I reported regression in VM. I used you filecache module
and discovered that the leaks are caused by these items:
# filecache 1.0
# ino size cached cached% refcnt state dev file
167302 16 16 100 1 d- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
167301 16 16 100 1 d- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
167300 16 16 100 1 d- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
167299 4 4 100 1 -- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
167290 8 8 100 1 -- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
167289 8 8 100 1 -- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
167288 16 16 100 1 -- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
167287 16 16 100 1 d- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
there are tons of those items:
cat /proc/filecache | grep drm | wc -l
14224
Do you have any clues what happens here? Is it a bug in kernel VM system or it
is more likely a bug in Intel's GEM drm driver? Right now it results in 500MB
of undropable cache.
Also lsof reports many leaked file descriptors:
lsof | grep drm | wc -l
7326
