| |
Hi, I found out that mutt when running with a 2.6.16-rcX kernel is unable to discover new mails in mboxes other than the main one. On my system mail is downloaded using fetchmail, which hands the mails to procmail; procmail then saves the mails in the correct mbox (for example each mailing list has its own mbox). Using mutt, the 'c' key is used to changed mbox and it defaults to the first mbox that has new mail. With kernel 2.6.16 'c' has no effects (mutt seems to think that there's no new mail).
I think that the problem is related to the changes in: fs/xfs/linux-2.6/xfs_iops.c
I've done a simple test with working and non working system:
* With kernel 2.6.16-rc2

Note that with 2.6.15 the atime of the mbox is unchanged after opening mutt, while with 2.6.16-rc2 it does change (I guess that's what confuses mutt).
Also, looking at strace mutt reads the mbox (so atime changes) but immediatly resets atime using utime:
