[PATCH v2 0/7] netfs: Miscellaneous fixes

[David Howells]

Hi Christian,

Here are some miscellaneous fixes for netfslib:

 (1) Fix triggering of a VM_BUG_ON_FOLIO() in netfs_write_begin().

 (2) Fix error handling in netfs_extract_user_iter().

 (3) Fix netfs_invalidate_folio() to clear the folio dirty bit if all dirty
     data removed.

 (4) Fix the handling of a partially failed copy (ie. EFAULT) into a
     streaming write folio.  Also remove the netfs_folio if a streaming
     write folio is entirely overwritten.

 (5) Fix netfs_read_gaps() to remove the netfs_folio from a filled folio.

 (6) Fix the calculation of zero_point in netfs_release_folio() to limit it
     to ->remote_i_size, not ->i_size.

 (7) Fix netfs_perform_read() to not disable streaming writes when writing
     to an fd that's open O_RDWR.

The patches can also be found here:

Thanks,
David
