[JFFS2] Track parent inode for directories (for NFS export) 2008-05-01T17:47:17+00:00 David Woodhouse dwmw2@infradead.org 2008-05-01T17:47:17+00:00 27c72b040c0be8f3704ed0b6b84c12cbba24a7e8 To support NFS export, we need to know the parent inode of directories. Rather than growing the jffs2_inode_cache structure, share space with the nlink field -- which was always set to 1 for directories anyway. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

[JFFS2] Quiet lockdep false positive. 2008-05-01T14:53:28+00:00 David Woodhouse dwmw2@infradead.org 2008-05-01T14:53:28+00:00 590fe34c47cb5c2d836ac76fabc5f160bf31a3f1 Don't hold f->sem while calling into jffs2_do_create(). It makes lockdep unhappy, and we don't really need it -- the _reason_ it's a false positive is because nobody else can see this inode yet and so nobody will be trying to lock it anyway.

[JFFS2] Fix jffs2_reserve_space() when all blocks are pending erasure. 2008-04-23T15:01:37+00:00 David Woodhouse dwmw2@infradead.org 2008-04-23T14:40:52+00:00 422b120238130307da64fa44c9fb722bfaf5f1af When _all_ the blocks were on the erase_pending_list, we could't find a block to GC from but there was no _actually_ free space, and jffs2_reserve_space() would get a little unhappy. Handle this case by returning -EAGAIN from jffs2_garbage_collect_pass(). There are two callers of that function -- jffs2_flush_wbuf_gc(), which will interpret it as an error and flush the writebuffer by other means, and jffs2_reserve_space(), which we modify to respond to -EAGAIN with an immediate call to jffs2_erase_pending_blocks() and another run round the loop.
