X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=404e4b43fdd6daa7b4a9f81bc7e4358281d763fa;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git md: allow a resync that is waiting for other resync to complete, to be aborted. If two arrays share a device, then they will not both resync at the same time. One will wait for the other to complete. While waiting, the MD_RECOVERY_INTR flag is not checked so a device failure, which would make the resync pointless, does not cause the resync to abort, so the failed device cannot be removed (as it cannot be remove while a resync is happening). So add a test for MD_RECOVERY_INTR.
