Subject: recursive lock-enter-deadlock
Date: Wed, 21 Nov 2001 11:19:13 +0100 (MET) [thread overview]
Message-ID: <XFMail.20011121111913.R.Oehler@GDImbH.com> (raw)
A short question (I don't have a recent 2.4.x at hand, currently):
Is this recursive lock-enter-deadlock (2.4.0) fixed in newer kernels?
Regards,
Ralf
void truncate_inode_pages(struct address_space * mapping, loff_t lstart)
{
unsigned long start = (lstart + PAGE_CACHE_SIZE - 1) >> PAGE_CACHE_SHIFT;
unsigned partial = lstart & (PAGE_CACHE_SIZE - 1);
repeat:
spin_lock(&pagecache_lock);
if (truncate_list_pages(&mapping->clean_pages, start, &partial))
goto repeat;
if (truncate_list_pages(&mapping->dirty_pages, start, &partial))
goto repeat;
if (truncate_list_pages(&mapping->locked_pages, start, &partial))
goto repeat;
spin_unlock(&pagecache_lock);
}
