2006-10-01[PATCH] r/o bind mounts: monitor zeroing of i_nlinkDave Hansen1-1/+1
Some filesystems, instead of simply decrementing i_nlink, simply zero it during an unlink operation. We need to catch these in addition to the decrement operations.

2006-10-01[PATCH] r/o bind mount prepwork: inc_nlink() helperDave Hansen1-1/+1

2006-10-01[PATCH] r/o bind mounts: unlink: monitor i_nlinkDave Hansen1-5/+5
When a filesystem decrements i_nlink to zero, it means that a write must be performed in order to drop the inode from the filesystem. We're shortly going to have keep filesystems from being remounted r/o between the time that this i_nlink decrement and that write occurs. So, add a little helper function to do the decrements. We'll tie into it in a bit to note when i_nlink hits zero.

cifs should not be overwriting an element of the aops structure, since the structure is shared by all cifs inodes. Instead define a separate aops structure to suit each purpose.

2006-01-08[PATCH] Fix and add EXPORT_SYMBOL(filemap_write_and_wait)OGAWA Hirofumi1-2/+1
This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it. See mm/filemap.c: And changes the filemap_write_and_wait() and filemap_write_and_wait_range(). Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite() returns error. However, even if filemap_fdatawrite() returned an error, it may have submitted the partially data pages to the device. (e.g. in the case of -ENOSPC) <quotation> Andrew Morton writes, If filemap_fdatawrite() returns an error, this might be due to some I/O problem: dead disk, unplugged cable, etc. Given the generally crappy quality of the kernel's handling of such exceptions, there's a good chance that the filemap_fdatawait() will get stuck in D state forever. </quotation> So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO. Trond, could you please review the nfs part? Especially I'm not sure, nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.
