------- Comment #6 from sandeen@redhat.com 2009-02-12 16:42 -------
dJust for the record; here are the paths we're stuck on:
livecd:
sys_fdatasync
do_fsync
vfs_fsync
filemap_fdatawrite
__filemap_fdatawrite_range
do_writepage
ext4_da_writepages
write_cache_pages
lock page
(currently locked by pdflush)
pdflush:
pdflush
background_writeout
writeback_inodes
generic_sync_sb_inodes
__writeback_single_inode
do_writepages
ext4_da_writepages
write_cache_pages
lock page
(currently loscked by livecd)
the pdflush wbc looks like:
[1]kdb> wbc 0xffff88007d4abe10
struct writeback_control at 0xffff88007d4abe10
bdi = (null) sync_mode 0 (NONE)
nr_to_write = 992 pages_skipped = 0
range_start 0, range_end 0
nonblocking 1 congestion 0 kupdate 0 reclaim 0
writepages 1 range_cyclic 1 more_io 0 no_update 1
and the livecd-creator fsync wbc looks like:
[1]kdb> wbc 0xffff880012821ea8
struct writeback_control at 0xffff880012821ea8
bdi = (null) sync_mode 1 (ALL)
nr_to_write = 9223372036854775689 pages_skipped = 0
range_start 0, range_end 9223372036854775807
nonblocking 0 congestion 0 kupdate 0 reclaim 0
writepages 1 range_cyclic 0 more_io 0 no_update 1
