[regression]2.6.38-rc6 with XFS still does consume all free space

[regression]2.6.38-rc6 with XFS still does consume all free space

[Otto Meier]

Hello,
on my System a "make modules_install" with kernel 2.6.38-rc6 has eaten up
all free Space on a XFS partition.

The free Space is

/dev/sda6             56472984  43613692  12859292  78% /

after make modules_install i get

/dev/sda6             56472984  56472964        20 100% /

with kernel 2.6.37.1 everything runs fine and df shows

/dev/sda6             56472984  43262256  13210728  77% /

any idea what is going on here?

bye Otto

Are you building the 2.6.38-rc6 kernel on some other kernel or are
you running 2.6..38-rc6?

Had you already built the kernel, or did the make command build the
kernel and all the modules before installing them?  Can you check
how much space the modules directory is actually using (i.e. using
du)?

Also, did you get an ENOSPC error?

No, all the known preallocation regressions have been fixed. can you
confirm that the kernel you are running has this commit in it?

b8fc826 xfs: speculative delayed allocation uses rounddown_power_of_2 badly

Cheers,

I did build a new newer Kernel and was running 2.6.38-rc6.

Yes the kernel I was running had this commit.

Sorry for not answering earlier,  I added my comments to your questions above.
