Illumos 4390 - I/O errors can corrupt space map when deleting fs/vol
4390 i/o errors when deleting filesystem/zvol can lead to space map corruption Reviewed by: George Wilson <[email protected]> Reviewed by: Christopher Siden <[email protected]> Reviewed by: Adam Leventhal <[email protected]> Reviewed by: Dan McDonald <[email protected]> Reviewed by: Saso Kiselkov <[email protected]> Approved by: Dan McDonald <[email protected]> References: https://www.illumos.org/issues/4390 https://github.com/illumos/illumos-gate/commit/7fd05ac Porting notes: Previous stack-reduction efforts in traverse_visitb() caused a fair number of un-mergable pieces of code. This patch should reduce its stack footprint a bit more. The new local bptree_entry_phys_t in bptree_add() is dynamically-allocated using kmem_zalloc() for the purpose of stack reduction. The new global zfs_free_leak_on_eio has been defined as an integer rather than a boolean_t as was the case with the related zfs_recover global. Also, zfs_free_leak_on_eio's definition has been inserted into zfs_debug.c for consistency with the existing definition of zfs_recover. Illumos placed it in spa_misc.c. Ported by: Tim Chase <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #2545
