The patch titled
Subject: fs: add i_blocksize()
has been added to the -mm tree. Its filename is
fs-add-i_blocksize.patch
This patch should soon appear at
http://ozlabs.org/~akpm/mmots/broken-out/fs-add-i_blocksize.patch
and later at
http://ozlabs.org/~akpm/mmotm/broken-out/fs-add-i_blocksize.patch
Before you just go and hit "reply", please:
a) Consider who else should be cc'ed
b) Prefer to cc a suitable mailing list as well
c) Ideally: find the original patch on the mailing list and do a
reply-to-all to that, adding suitable additional cc's
*** Remember to use Documentation/SubmitChecklist when testing your code ***
The -mm tree is included into linux-next and is updated
there every 3-4 working days
------------------------------------------------------
From: Fabian Frederick <fabf@xxxxxxxxx>
Subject: fs: add i_blocksize()
Replace all 1 << inode->i_blkbits and (1 << inode->i_blkbits) in fs branch
This patch also fixes multiple checkpatch warnings: WARNING: Prefer
'unsigned int' to bare use of 'unsigned'
Thanks to Andrew Morton for suggesting more appropriate function instead
of macro.
