asynchronous crypto hadsh API. - Fix to both DM crypt and DM integrity targets to discontinue using CRYPTO_TFM_REQ_MAY_SLEEP because its use of GFP_KERNEL can lead to deadlock by recursing back into a filesystem. - Various DM raid fixes related to reshape and rebuild races. - Fix for DM thin-provisioning to avoid data corruption that was a side-effect of needing to abort DM thin metadata transaction due to running out of metadata space. Fix is to reserve a small amount of metadata space so that once it is used the DM thin-pool can finish its active transaction before switching to read-only mode. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJbmq1sAAoJEMUj8QotnQNa9hwIANBzgefmIoBA8hCqlS7Nzogh moHAbaUONYxAVksJ5s4Divpa4RE8jSZ8AiVJizbLj94XxqnpA5x4pmhtUs3OdWxq 4FW8fZvb2L1IMeshajMsO+rKrL6y8uwYnRI5zSJRKxhV2frj1VZ4ioMEXMGrwqjO jwNYFWglX5G3eIohUIDxgXki/WkacndQlsy2T6Utx0idz50usOt1pNON/GPhRsXd yWbvxQWuaZlm6+TF1ygsrXr1nMwRwDw0pdjY9sRQ3hHmuYQ24Wgkwf5Ggi5US7VZ iwgK8dppR8zWqwRyxRYahJvQvwcnC18mewFAmuDQfvPXqvUHtuhWaxzE4D9c3L0= =yIoD -----END PGP SIGNATURE----- Merge tag 'for-4.19/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - DM verity fix for crash due to using vmalloc'd buffers with the asynchronous crypto hadsh API. - Fix to both DM crypt and DM integrity targets to discontinue using CRYPTO_TFM_REQ_MAY_SLEEP because its use of GFP_KERNEL can lead to deadlock by recursing back into a filesystem. - Various DM raid fixes related to reshape and rebuild races. - Fix for DM thin-provisioning to avoid data corruption that was a side-effect of needing to abort DM thin metadata transaction due to running out of metadata space.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
